King Taco is a fast food restaurant chain headquartered in Los Angeles, California, which offers a variety of Mexican-inspired dishes.

King Taco was founded in 1974 by Raul Martínez, Sr., who operated a mobile lunch wagon out of a converted ice cream truck.

Other locations soon followed, opening every other year in Commerce, Baldwin Park, El Monte and other East Los Angeles sites.

Called the King Taco 500, the race was eventually canceled as a result of the forest fires that devastated the Southern California area at the time.
