The MIT License is a permissive software license originating at the Massachusetts Institute of Technology (MIT) in the late 1980s. As a permissive license, it puts few restrictions on reuse and has high license compatibility.

Unlike copyleft software licenses, the MIT License allows reuse within proprietary software, provided that all copies of the software or its substantial portions include a copy of the terms of the MIT License and also a copyright notice. In 2015 and from at least 2020 through 2025, the MIT License was the most popular software license on GitHub.
