Apache软件基金会（Apache Software Foundation，简称ASF）是一个非营利组织，致力于支持和发展开源软件项目。ASF成立于1999年，总部位于美国加利福尼亚州的Forest Hill，它是一个由志愿者组成的全球性组织，拥有超过300名成员和数百名志愿者。
ASF的使命是通过开源软件的方式，为全球提供自由、开放、创新的技术解决方案。ASF通过为开源项目提供法律、技术和社区支持等多方面的帮助，帮助开源项目得到长期发展和成功，同时也保护了开源项目的知识产权和社区的利益。
ASF的管理模式非常开放和民主，它采用“基于社区”的开发模式，即由社区成员共同参与项目的开发、维护和治理。ASF的所有项目都遵循Apache许可证（Apache License），这是一种宽松的开源许可证，允许商业和非商业用户自由使用、修改和分发ASF的开源软件项目。
ASF是世界上最大的开源组织之一，旗下拥有数百个开源项目，包括Apache服务器、Hadoop、Tomcat、Lucene、Struts等，这些项目被广泛应用于企业、政府、教育和科研等领域，成为了全球开源软件领域的佼佼者。
