The Academic Free License (AFL) is a permissive free software license written in 2002 by Lawrence E. Rosen, general counsel of the Open Source Initiative (OSI).

The license grants similar rights to the BSD, MIT, UoI/NCSA and Apache licenses — licenses allowing the software to be made proprietary — but was written to correct perceived problems with those licenses:

*The AFL makes clear what software is being licensed by including a statement following the software's copyright notice;
*The AFL includes a complete copyright grant to the software;
*The AFL contains a complete patent grant to the software;
*The AFL makes clear that no trademark rights are granted to the licensor's trademarks;
*The AFL warrants that the licensor either owns the copyright or is distributing the software under a license;
*The AFL is itself copyrighted, with the right granted to copy and distribute without modification.

AFL versions 1.2 and 2.1 are not compatible with the GNU GPL. [cite web|url=http://www.gnu.org/licenses/license-list.html |title=Various Licenses and Comments about Them |accessdate=2007-07-07 |last=Richard |first=Stallman |publisher=Free Software Foundation ] The Free Software Foundation has not commented on the newer version 3.0, which Eric S. Raymond contends is GPL compatible. In late 2002, an OSI working draft considered it a "best practice" license.
