StuffIt is a discontinued family of computer software utilities for archiving and compressing files. Originally produced for Macintosh, versions for Microsoft Windows, Linux (x86), and Sun Solaris were later created.^[1][2] The proprietary compression format used by the StuffIt utilities is also termed StuffIt.

In December 2019, Smith Micro Software, the product's most-recent owner and developer, officially announced that StuffIt had reached its end-of-life and that StuffIt products would no longer be developed.^[3] One last update did come out in December 2020 after the launch of the Apple M1 architecture to support that and Intel Mac systems through a universal binary of the program.
