Yogi's Ark Lark is a 1972 American animated television special produced by Hanna-Barbera Productions, intended to raise ecological awareness. Written by Bob Ogle and Dick Robbins and directed by Joseph Barbera and William Hanna, it was broadcast on ABC on September 16, 1972, as part of The ABC Saturday Superstar Movie and served as the two-part episode for Yogi's Gang.

Aside from its environmental message, the film marked a milestone in Hanna-Barbera's history: a wide range of the studio’s characters were united in one story for the first time. This set the tone for future series and specials, such as Laff-A-Lympics and Yogi's First Christmas.
