Crusader Rabbit is an American animated series created by Alexander Anderson and Jay Ward, and the first of its kind to be produced specifically for television. Its main characters were Crusader Rabbit and his sidekick Ragland T. Tiger, or "Rags". The stories were four-minute-long satirical cliffhangers.

The concept was test marketed in 1948, while the initial serial – Crusader vs. the State of Texas – aired on KNBH in Los Angeles beginning on August 1, 1950 (not August 1, 1949 as some sources erroneously state). The program was syndicated from 1950 to 1951 for 195 episodes, then was revived in 1959 for 260 color episodes. Ward, who later went on to create The Adventures of Rocky and Bullwinkle and Friends, was involved as business manager and producer.
