NCSA开源协议的英文全称为：University of Illinois/NCSA Open Source License。是一个宽松的自由软件许可证，基于MIT/X11许可证和三类BSD许可证。通过结合这两个许可证的部分内容，它试图比任何一个都更清晰、更简洁。通常叫做：伊利诺伊大学/NCSA开源许可证。
该许可证是2001年成立的伊利诺斯大学委员会努力的结果。其目的是为国家超级计算应用中心（NCSA）和全球软件社区创建一个新的许可标准。在2002年3月28日的开放源代码促进会（OSI）董事会会议上，它被正式认证为开源许可证。
在NCSA许可下的源代码可以被合并到专有产品中，而不需要CopyLeft自由软件许可所提出的互惠要求。该许可证与所有版本的GNU通用公共许可证兼容。值得注意的使用该许可证的软件包括LLVM和Clang（v8.0.1或更早版本）。
以下是license原文模板。在实际许可证中，将填写尖括号内的部分（年份，所有者组织名称等）。

与其他许可证的比较
伊利诺伊大学/NCSA开源许可证是基于模板的，就像MIT/X11和BSD许可证一样。初始许可授予基于麻省理工学院许可的文本；它清楚地声明它适用于软件和任何相关的文档文件，并且比BSD许可证更具体地说明了所传达的权利。
这三个许可条款几乎与修改后的BSD许可条款相同。它要求重新发布复制许可证，并防止贡献者的名字在未经许可的情况下被用来推广衍生产品。这里，它比MIT许可证更精确，后者不区分源代码形式或对象形式的再分发。
伊利诺伊大学/NCSA开源许可证启发了OSI的Lawrence Rosen创建学术自由许可证，其比BSD、MIT和NCSA许可证更复杂，并且涵盖了专利和商标法等其他领域。
