Robert Emerson Clampett Sr. (May 8, 1913 – May 2, 1984) was an American animator, director, producer and puppeteer. He was best known for his work on the Looney Tunes animated series from Warner Bros. as well as the television shows Time for Beany and Beany and Cecil. He was born and raised not far from Hollywood and, early in life, showed an interest in animation and puppetry. After dropping out of high school in 1931, he joined the team at Harman-Ising Productions and began working on the studio's newest short subjects, Looney Tunes and Merrie Melodies.

Clampett was promoted to a directorial position in 1937. During his 15 years at the studio, he directed 84 cartoons later deemed classic, and designed some of the studio's most famous characters, including Porky Pig, Daffy Duck and Tweety. Among his most acclaimed films are Porky in Wackyland (1938) and The Great Piggy Bank Robbery (1946). He left Warner Bros. Cartoons in 1945 and turned his attention to television, creating the puppet show Time for Beany in 1949. A later animated version of the series, Beany and Cecil, was initially broadcast on ABC in 1962 and rerun until 1967. It is considered the first fully creator-driven television series and carried the byline "a Bob Clampett Cartoon".

In his later years, Clampett toured college campuses and animation festivals as a lecturer on the history of animation. His Warner cartoons have seen renewed praise in decades since for their surrealistic qualities, energetic and outrageous animation, and irreverent, wordplay-laden humor. Animation historian Jerry Beck lauded Clampett for "putting the word 'looney' in Looney Tunes."
