Hanna-Barbera Cartoons (Formerly known at various times as H-B Enterprises, H-B Production Company and Hanna-Barbera Productions, Inc.) was an American animation studio that dominated American Television animation for nearly four decades in the mid-to-late 20th century. It was formed in 1957 by former MGM cartoon directors William Hanna and Joseph Barbera (creators of Tom and Jerry) in partnership with Anchors Aweigh director George Sidney.

Hanna-Barbera co-produced The Tom and Jerry Show (1975) with MGM Television as well as Tom & Jerry Kids with Turner Entertainment.

Hanna-Barbera was bought by Taft Broadcasting in 1966, and later sold to Turner in 1991.

In 2000, Hanna-Barbera produced only one stand-alone Tom and Jerry short for television, which is "The Mansion Cat", which premiered on Cartoon Network and Boomerang in 2001. The studio closed in 2001 following the death of co-founder William Hanna. Following the closure of Hanna-Barbera Productions, the studio was soon after absorbed by Warner Bros. as a name-only unit for Hanna-Barbera's animated properties, such as Scooby-Doo.
