Krewe of King Arthur is a coed New Orleans Mardi Gras krewe.

The Krewe of King Arthur was formed in 1977 by the youngest Carnival captain in history, Philip Fricano, Jr. It was the first Westbank men's organization to parade at night in 1979.

In 2001, King Arthur moved its parade from the Westbank to the current Uptown New Orleans route.

In 2022, King Arthur made history with its largest membership ever, at over 2,400 riders. According to Mardi Gras Guide, it is the third largest krewe in New Orleans and the largest Krewe on the first weekend of Mardi Gras
