• Country-specific tags
• GNU licenses
• Free Creative Commons licenses
• Various free licenses
• Not free or uncertain
• Descriptive tags
• Index by source

A Creative Commons (CC) license enables free distribution of a copyrighted work such as a photograph, drawing, video etc. Files with Creative Commons Attribution (by) and Creative Commons Attribution-ShareAlike (by-sa) licenses may be uploaded to Wikimedia Commons. However, they must not include Non-Commercial (nc) or No-Derivatives (nd) restrictions. {{CC-zero}} and {{CC-PD}} licenses are also accepted. All files with a Creative Commons license should have a tag showing which license applies.

Earlier versions of the Creative Commons licenses included "ports", where they were adapted to the copyright laws of specific countries. Version 4.0 of the Creative Commons licenses, released on November 25, 2013, are generic licenses that are applicable to most jurisdictions. Creative Commons has suspended the porting program and recommends use of the unported 4.0 licenses, as does Wikimedia.

A partial list of Creative Commons license tags is given below. See Commons:Creative Commons copyright tags for a full list of allowed licenses. These include country specific licenses such as {{Cc-by-sa-3.0-vn}} that are based on the copyright laws of the country of origin, and more than 500 custom licenses such as {{ESA-Hubble}} that typically apply to files from a given source.
