JFFS2 (Journaling Flash File System version 2) is a file system for use in the Linux operating system for flash memory devices. It is a successor to JFFS. It has been included in the Linux kernel since 2001. LogFS, UBIFS, and YAFFS have been developed as replacements for it.

JFFS2 has similar characteristics to JFFS, but introduces some enhancements such as support for NAND flash devices and compression.
