The Mormon cricket is a large insect native to western North America in rangelands dominated by sagebrush and forbs. Anabrus is a genus in the shield-backed katydid subfamily in the Tettigoniidae family, commonly called katydids, bush crickets, and previously "long-horned grasshoppers". Its common name, "Mormon cricket", is a misnomer: true crickets are of the family Gryllidae.

The Tettigoniinae are a subfamily of bush crickets or katydids, which contains hundreds of species in about twelve tribes.
