What is the name of the largest pizza chain by number of locations worldwide?

Domino's Pizza is the largest pizza chain worldwide by number of locations.

Domino's began in 1960 when Tom Monaghan and his brother James bought a small Michigan pizzeria called DomiNick's. Tom later received control of the business and renamed it Domino's Pizza in 1965. Its franchise-based delivery model helped the company expand rapidly across the United States and internationally.

The chain is often confused with Pizza Hut because Pizza Hut was historically the larger brand by store count and remains one of the world's biggest pizza companies. Domino's, however, has surpassed it in global locations in recent years. The comparison can change as chains open or close restaurants, but Domino's currently leads the major international pizza brands by location count.
