PizzaExpress is a well-known British international chain of pizzerias that has established itself not just in the UK but also in other countries. The company, which Peter Boizot founded in 1965, has grown rapidly, now having over 470 locations in the United Kingdom and 100 abroad in Singapore, Hong Kong, China, India, Indonesia, Kuwait, the Philippines, and the United Arab Emirates. Boizot's journey to Italy, during which he brought back to London a pizza oven from Naples and a chef from Sicily, sparked the brand's creation and signalled the start of a pizza revolution in the UK.

PizzaExpress has long been a leader in the casual dining sector, delivering cutting-edge concepts and menu items. The company is well-known for its homemade, authentically Italian pizza. PizzaExpress added the lighter pizza Leggera, the first pizza queue on the high street, to its traditional pizza choices. This pizza range has about 500 calories. Additionally, the company started a Guest Chef Series, working with well-known chefs to develop unique meals for its menu.

PizzaExpress has a long history of supporting the arts and neighbourhood projects in addition to providing great meals. The company founded its first jazz venue in Dean Street, London, in 1969, and has subsequently promoted the jazz scene by organising performances by musicians including Amy Winehouse and Ella Fitzgerald. By contributing a portion of each pizza sale to the Venice in Peril Fund, PizzaExpress launched the Pizza Veneziana in 1977 to aid in the effort to save Venice from sinking. The company also has a Schools Programme that uses its restaurants as classrooms to teach kids about using fresh ingredients, managing a small business, and preparing their meals.
