IronPython是一种在.NET和Mono上实现的Python语言，由Jim Hugunin（同时也是Jython创造者）所创造。1.0版于2006年9月5日发布。

随后，在2007年，开发者决定改写构架，使用动态类型系统以让更多脚本语言能很容易地移植到.NET Framework上。2008年，随着微软发布.NET Framework 3.0/3.5、Silverlight之后，IronPython也发布了2.0版，目前最新版本是2.7，于2011年3月发布，支持.NET Framework 4.0。

IronPython is an implementation of the Python programming language targeting the .NET Framework and Mono. Jim Hugunin created the project and actively contributed to it up until Version 1.0 which was released on September 5, 2006. Thereafter, it was maintained by a small team at Microsoft until the 2.7 Beta 1 release; Microsoft abandoned IronPython (and its sister project IronRuby) in late 2010, after which Hugunin left to work at Google. IronPython 2.0 was released on December 10, 2008. The project is currently maintained by a group of volunteers at Microsoft's CodePlex open-source repository. It is free and open-source software, and can be implemented with Python Tools for Visual Studio, which is a free and open-source extension for free, isolated, and commercial versions of Microsoft's Visual Studio IDE.
