Crafty is a chess program written by UAB professor Robert Hyatt, with development and assistance from Michael Byrne, Tracy Riegle, and Peter Skinner.

Tord Romstad, co-author of Stockfish, described Crafty as "arguably the most important and influential chess program ever".

[citation needed] Crafty also finished in second place in the 2010 World Computer Rapid Chess Championships.

[citation needed] In the World Computer Chess Championships 2004, running on slightly faster hardware than all other programs, Crafty took fourth place with the same number of points as the third-place finisher, Fritz 8.

Special editions of the program include enhanced features such as an opening book, positional learning, and an endgame tablebase.
