The family Gryllidae contains the subfamilies and genera which entomologists now term true crickets. Having long, whip-like antennae, they belong to the Orthopteran suborder Ensifera, which has been greatly reduced in the last 100 years (e.g. Imms): taxa such as the spider-crickets and allies, sword-tail crickets, wood or ground crickets and scaly crickets have been elevated to family level. The type genus is Gryllus and the first use of the family name "Gryllidae" was by Francis Walker.

They have a worldwide distribution (except Antarctica). The largest members of the family are the 5 cm (2 in)-long bull crickets (Brachytrupes) which excavate burrows a metre or more deep. The tree crickets (Oecanthinae) are delicate white or pale green insects with transparent fore wings, while the field crickets (Gryllinae) are robust brown or black insects.

Many taxa in the Ensifera may be called crickets sensu lato, including the Rhaphidophoridae – cave or camel crickets; Stenopelmatidae – Jerusalem or sand crickets; Mogoplistidae – scaly crickets; Gryllotalpidae – mole crickets; Anabrus – Mormon crickets; Myrmecophilidae – ant crickets; and Tettigoniidae – the bush crickets or katydids.
