The ISC license is a permissive free software license written by the Internet Systems Consortium (ISC). It is meant to be functionally equivalent to the simplified BSD and the MIT licenses, differing in its removal of language deemed unnecessary following the global adoption of the Berne Convention.

Before accepting the license as a free software license, the Free Software Foundation asked for clarification of the text. In July 2007, as a result, "and distribute" was changed to "and/or distribute".
