USENIX is an American 501(c)(3) nonprofit membership organization based in Berkeley, California and founded in 1975 that supports advanced computing systems, operating system (OS), and computer networking research. It organizes several conferences in these fields.


USENIX was established in 1975 under the name "Unix Users Group," focusing primarily on the study and development of the Unix OS family and similar systems. In June 1977, a lawyer from AT&T Corporation informed the group that they could not use the word "Unix" in their name as it was a trademark of Western Electric (the manufacturing arm of AT&T until 1995), which led to the change of name to USENIX. Since its founding, it has published a technical journal titled ;login:.

USENIX was started as a technical organization. As commercial interest grew, a number of separate groups started in parallel, most notably the Software Tools Users Group (STUG), a technical adjunct for Unix-like tools and interface on non-Unix operating systems, and /usr/group, a commercially oriented user group.

USENIX's founding President was Lou Katz.


USENIX hosts numerous conferences and symposia each year, including:


USENIX publishes a magazine called ;login: that appears four times a year. From 2021, it has become an all-digital magazine and openly accessible. ;login: content informs the community about practically relevant research, useful tools, and relevant events.

From 1988–1996, USENIX published the quarterly journal Computing Systems, about the theory and implementation of advanced computing systems in the UNIX tradition. It was published first by the University of California Press, then by the MIT Press. The issues have been scanned and are online.

Open access

USENIX conferences became open access in 2008. Since 2011, they have provided audio and video recordings of paper presentations and conference talks in their open-access materials, free of charge.

USENIX Lifetime Achievement Award

This award, also called the "Flame" award, has been presented since 1993.

And it wasn't the first meeting, either, as Lou Katz had run a small meeting in a conference room at Columbia in May 1974. But there were "about 40 people from 20 institutions" at the 1975 meeting.
