Pyramid was a gaming magazine, publishing articles primarily on role-playing games, but including board games, card games, and other sorts of games. It began life in 1993 as a print publication of Steve Jackson Games for its first 30 issues, though it has been published on the Internet since March 1998. Print issues were bimonthly; the first online version published new articles each week; the second online version is monthly. Pyramid is headquartered in Austin, Texas. It replaced Steve Jackson Games' previous magazine Roleplayer.

Pyramid features general gaming articles by freelance authors, as well as Designer's Notes by Steve Jackson Games product developers, industry news, cartoons, and gaming product reviews. Although articles tend to concentrate on Steve Jackson Games products such as GURPS, it has published articles on other games such as d20 System, Talisman, Nobilis, Hero System, and has featured various comic strips and single-panel cartoons (currently Murphy's Rules). Steve Jackson Games also briefly published another online magazine, d20 Weekly for several months using a very similar model to that of Pyramid. However, the venture was not a success, and was eventually folded into a slightly expanded Pyramid.

The online subscription system used for Pyramid also granted access to subscriber forums, a dedicated chat server, and occasional pre-publication playtest material for Steve Jackson Games and other companies' products. In 2008 this was changed: Pyramid became available as a PDF download from e23 (online service), and the subscriber forums have been discontinued. Access to playtest material is contingent on participation in an actual playtest.

In late 2018, it was announced on the Pyramid page of the Steven Jackson Games website that "we are closing down Pyramid magazine later this year. The December 2018 issue will be the final issue of the magazine, and effective immediately, we are no longer accepting subscriptions."
