C Traps and Pitfalls is a slim computer programming book by former AT&T Corporation researcher and programmer Andrew Koenig, its first edition still in print in 2017, which outlines the many ways in which beginners and even sometimes quite experienced C programmers can write poor, malfunctioning and dangerous source code.

It evolved from an earlier technical report, by the same name, published internally at Bell Labs.[1] This, in turn was inspired by a prior paper given by Koenig on "PL/I Traps and Pitfalls" at a SHARE conference in 1977. Koenig wrote that this title was inspired by a 1968 science fiction anthology by Robert Sheckley, "The People Trap and other Pitfalls, Snares, Devices and Delusions, as Well as Two Sniggles and a Contrivance".[2]
