Linux 基金会（英语：Linux Foundation，简称 LF），是一个非盈利性的联盟，其目的在于推动Linux的成长。

在2007年，开源码发展实验室（Open Source Development Labs, OSDL)与自由标准组织（Free Standards Group, FSG)联合起来，成立了这个组织。

The Linux Foundation (LF) is a non-profit technology trade association chartered to promote, protect and advance Linux and collaborative development. Founded in 2007 by the merger of the Open Source Development Labs (OSDL) and the Free Standards Group (FSG), the Linux Foundation sponsors the work of Linux creator Linus Torvalds and is supported by leading Linux and open source companies, including prominent technology corporations such as Fujitsu, HP, IBM, Intel, NEC, Oracle, Qualcomm and Samsung, and developers from around the world. In recent years, The Linux Foundation has expanded its services through events, training and certification and Collaborative Projects. Examples of Collaborative Projects at Linux Foundation include OpenDaylight, Open Platform for NFV (OPNFV), AllSeen Alliance, Cloud Foundry and Node.js Foundation.
