Trenton tomato pie[1][2] or New Jersey tomato pie[3] is a type of circular, thin-crust Italian tomato pie created in Trenton, New Jersey, United States, around the early 20th century in which cheese and other toppings are added on first, then the sauce.

Unlike the thicker square Italian tomato pie, Trenton tomato pie is often circular, of the thin-crust variety and includes cheese.

[6] The first tomato pies in the United States were sold in New York City[7] at Lombardi's which opened in 1905.

[8] Papa's Tomato Pies, whose proprietor learned the trade at Joe's, was opened two years later in 1912.

[9] The Trenton region is home to the two oldest currently operating New Jersey tomato pie restaurants in the United States, Papa's and De Lorenzo's.
