The Banana Splits Adventure Hour (also known simply as The Banana Splits) is an American television variety show produced by Hanna-Barbera Productions and featuring the Banana Splits, a fictional rock band composed of four costumed animal characters in red helmets. The costumed hosts of the show are Fleegle (guitar, vocals), Bingo (drums, vocals), Drooper (bass, vocals) and Snorky (keyboards, effects).

The series ran for 31 episodes on NBC Saturday mornings from September 7, 1968, to September 5, 1970, and in syndication from 1971 to 1982. The show features the Banana Splits band as live-action costumed characters, who host both live-action and animated segments within their program. The Banana Splits was Hanna-Barbera's first series to feature live action with animation, following a 1967 telefilm, Jack and the Beanstalk, which did the same. The costumes and sets were designed by Sid and Marty Krofft, and the series' sponsor was Kellogg's Cereals.

A feature-length comedy horror film adaptation called The Banana Splits Movie premiered at the San Diego Comic-Con on July 18, 2019, and was released worldwide on August 27, 2019.
