Apache许可证（英语：Apache License），是一个由Apache软件基金会发布的自由软件许可证，最初为Apache http服务器而撰写。Apache许可证要求被授权者保留版权和放弃权利的声明，但它不是一个反版权的许可证。

此许可证最新版本为“版本2”，于2004年1月发布。

Apache许可证在Apache社区内外被广泛使用。Apache基金会下属所有项目都使用Apache许可证，许多非Apache基金会项目也使用了Apache许可证：据统计，截至2012年10月，在sourceforge上有8708个项目使用了Apache许可证。

The Apache License (ASL) is a permissive free software license written by the Apache Software Foundation (ASF). The Apache (/əˈpætʃi/) License requires preservation of the copyright notice and disclaimer. Like other free software licenses, the license allows the user of the software the freedom to use the software for any purpose, to distribute it, to modify it, and to distribute modified versions of the software, under the terms of the license, without concern for royalties. The ASF and its projects release the software they produce under the Apache License and many non-ASF projects are also using the ASL.
