Soup or Sonic is an animated cartoon in the Merrie Melodies series, starring Wile E. Coyote and the Road Runner. It was first aired on May 21, 1980 as a part of the television special Bugs Bunny's Bustin' Out All Over and was one of three new cartoons released. This is the only canonical cartoon in which Wile E. Coyote catches the Road Runner without him escaping afterward, although due to the existing circumstances, Wile E. is physically unable to actually eat the Road Runner.

"Soup or Sonic" was directed by Chuck Jones and Phil Monroe. The title is a homophonic variation, a play on the terms "supersonic" and 'soup or salad', as one might be offered by a waiter in a restaurant. In comparison to other episodes, this is the longest episode, with a length of 9 minutes and 11 seconds.
