QGIS Trademark and brand guidelines

We’re thrilled that you want to refer to either the QGIS project or QGIS.ORG association and sincerely appreciate your help in spreading the word.

This page aims to provide you with all the information and resources you need for a correct use of the QGIS brand assets.

The QGIS name and logo are protected under European law from unauthorized and confusing uses of the trademark. You can find our trademark information at OAMI and EUIPO. Our main aim is to encourage those who do business using QGIS name and logo to participate actively in the project and help us to improve QGIS.

QGIS trademarks, service marks, logos and designs, as well as other works of authorship that are eligible for copyright protection (collectively termed “Marks”) are valuable assets that QGIS.ORG needs to protect. QGIS.ORG does not permit all uses of QGIS Marks. QGIS.ORG has posted these Trademark Usage Guidelines (“Guidelines”) to assist you in properly using our Marks in the specific cases that we do permit. The strength of our Marks depends, in part, upon consistent and appropriate use. We ask that you properly use and credit our Marks in accordance with these Guidelines. We reserve the right to change these Guidelines at any time solely at our discretion.

These Guidelines should be followed along with all QGIS’s rules and policies, posted on QGIS.ORG website or otherwise.

Country Voting Members

QGIS.ORG permits official QGIS country user groups, to modify the QGIS logo and use the modified QGIS logo for non-commercial communications and projects. This permission is subject to continued compliance with these Guidelines, QGIS Trademark Guidelines and all other rules and policies. QGIS reserves the right to cancel or change this permission at any time at its sole discretion. If you would like to use a modified version of the QGIS logo, please submit your artwork for approval at trademark@qgis.org. Upon approval, you will receive a license agreement to sign before you may begin using the artwork.

QGIS.ORG also permits its official country user groups, to register a QGIS Top Level Domain (qgis.ch, qgis.dk etc.) according to the rules further down in this document.

Examples of use that do not require permission

In cases of fair use, you may use or refer to QGIS trademark without explicit permission from QGIS.ORG. The following are examples of such permitted usages:

  • Livres, articles, tutoriels : si vous écrivez des articles, des livres, des articles de blog, des tutoriels, du matériel d’étude pour l’université et autres documents similaires vos n’avez pas besoin de permission pour citer le nom de QGIS et d’utiliser son logo.


We require you to give attribution to the QGIS project and reference the project website somewhere in your book, article, etc. This could be a short paragraph in the Introduction or Preface. Avoid anything that may give the impression that your work is an official QGIS product.

  • Courses, training: If you present a course on QGIS, in either an academic, free, or commercial context, you can use the logo and the name ‘QGIS’ in course material.


Please routinely explain in your course materials that QGIS is free and open source software, and actively encourage anyone to contribute, directly or indirectly, to the project.

  • Services: If you provide services (support, development) on QGIS, you can use QGIS trademark to describe or advertise your services or products relating to QGIS, provided this is done in a way that is not misleading (see requirements for product names below.)
  • Linking: If you use the QGIS logo on a website linking to our websites (https://QGIS.org) or any of our domains, or github, you do not need special permission.
  • Merchandise: You can make t-shirts, desktop wallpapers, caps, or other merchandise with QGIS trademark for non-commercial usage. You can also make merchandise with QGIS trademark for commercial usage provided that you truthfully advertise to customers which part of the selling price, if any, will be donated to the QGIS project. See our donations page for more information on how to donate to the QGIS project.

Examples of use requiring a permission

Some uses of our trademark require the user to obtain a permission. If you need a permission, please fill out our form (https://goo.gl/forms/b57Rg6IyFy0FC47p2).


A permission is not a formal endorsement of your QGIS related project and doesn’t constitute a statement on the quality of your service.

  • Product names: If you plan to market a QGIS-based product or service to the public using a trademark or name that includes the word “QGIS”, such as “YourCompany QGIS” you are required to apply for and obtain a permission from the QGIS Project Steering Committee (QGIS-PSC). This is true whether or not you apply to register your trademark with a government. When developing and advertising QGIS-based products, we ask you to follow the following guidelines:
    1. Don’t present your work as our work: If you provide a customized QGIS version, make it clear that your offer is a derivative product, and not the official QGIS version by adding your company or brand name to the product name and accompanying text explaining that your product is a derivative as needed.
    2. Don’t present our work as your work: Give credit to the QGIS project where due. Don’t hide the fact that your product is based on QGIS.
    3. Good product name examples include:
      • VotreSociété QGIS
      • Application/Suite VotreSociété basée sur QGIS
      • VotreMarque alimentée par QGIS
      • VotreMarque basée sur QGIS
    4. Bad product name examples include:
      • YourCompany GIS
      • QGIS special edition


When referring to QGIS please do not undermine the validity of the main QGIS project. We prefer that you refer to our software packages as “Official Packages” and not “Community Releases” or similar. If you create your own packages, please make it clear that these are derivative packages and not created or endorsed by the QGIS project.

  • Domain names and websites: Proper use of our Marks on websites to name or accurately describe QGIS’s products, services or technology is permitted. The use of our Marks should not be misleading or likely to cause confusion as to whether the website is sponsored by or affiliated with QGIS or whether the products, services or technology are offered by QGIS. QGIS Reserves the right to request you to remove our mark from your domain name, web site or publication if we deem it’s use to be inappropriate.
    1. Companies, products, and commercial projects cannot use a qgis.tld (top level domain): Any principal or secondary level domain name, with or without commercial intent, should not be identical to or virtually identical to any of our Marks.
    2. Companies, products, and commercial projects should preferably not to use ****qgis****.xxxx: The website owner should not register any domain name containing our Marks and should not claim any trademark or similar proprietary rights in the domain name. For example, “QGIStech.com”, “QGIS-group.com”, “QGISexperts.com” are not allowed without asking for permission. Any violation of this policy may result in legal action. The website should otherwise comply with domain name registry policies and applicable laws regarding trademark infringement and dilution.
    3. Exceptions:
      • QGIS.ORG Country voting members should use ccTLD (QGIS.ch, QGIS.dk, …)
      • Non-commercial projects can use qgis.xxxxx (qgis.tutorials would fall into this category if the tutorials are free) but should ask for permission before registering the domain. QGIS.ORG may register the domain and point it to the name servers provided by the requestor or instruct the requestor to do so.


Une autorisation n’est pas une approbation formelle de la part du projet QGIS et n’a pas de signification sur la qualité de service.

  • Social Media

Any and all use of our Marks in connection with account names, profiles, avatars or handles on social media platforms is subject to the same guidelines set forth herein as for other uses. The use of any of our Marks in an account name, profile name, as an avatar, or in a handle on social media platforms requires a permission request.

Foire Aux Questions

Q: Quand ai-je besoin d’afficher une référence au projet ?

A: Whenever and however you use the term QGIS in print, on the internet, or in audio broadcasts, you should always give proper attribution to QGIS project. For more information see “Trademark Attribution.”

Q: I am registering or have registered a trademark with my country’s trademark authority. Do I still need a permission?

A: Yes, assuming your trademark includes the element QGIS and it is being used in connection with software-related goods and services. Please note, the permission applies to QGIS trademark whether or not they are registered with a trademark authority. If you are using the term QGIS as a trademark (whether or not registered), you need to apply for a permission.

Q: I am a commercial entity (for example, a company, partnership or sole proprietor, profit or non-profit) selling software-related goods or services and using the word “QGIS” in the entity’s name. Do I need to apply for a permission?

A: Using QGIS in the entity’s name is not permitted because you are using QGIS as part of a trademark in connection with software-related goods or services. Software-related goods are computer programs and systems, or packages bundling software with tools, utilities, hardware, etc. Software-related services are services that deploy, document, facilitate the use of, or enhance computer programs and systems. Even if you don’t use QGIS as part of the entity’s name, if the entity has a product or service (whether sold or given away for free) that uses “QGIS” in its name, you still need a permission for the use of the word QGIS in the name of the products or services.

Q: Si je dispose d’une autorisation pour ma marque, est-ce-que QGIS refusera d’accorder des autorisations similaires aux marques qui sont identiques ou proches de la mienne ?

A: No, QGIS will not attempt to ensure exclusivity or protect marks from infringement. QGIS considers the protection of trademarks against infringement to be the responsibility of the trademark owner. QGIS is not a dispute resolution authority, and does not become involved in disputes between trademark owners.

Q: Consentement d’Enregistrement de Marque: Mon organisation a fait une demande d’enregistrement de marque pour des biens ou des services logiciels qui incluent QGIS comme élément. La demande a été rejetée pour risque de confusion avec la marque QGIS. Si je demande une autorisation est-ce-que QGIS consentira à m’enregistrer ?

A: No. The QGIS permission is not a consent for the registration of other trademarks. To protect the QGIS mark from dilution, we do not consent to the registration of trademarks found to be confusingly similar to the QGIS mark.
