National Pizza Party Day

National Pizza Party Day, observed on the third Friday of May, is a delicious invitation to gather with friends, family, or coworkers and enjoy one of the world’s most beloved comfort foods. Whether you prefer a classic cheese pizza, a crisp vegetable topping, or an adventurous combination, the day celebrates the simple pleasure of sharing a meal and making memories around the table.

It’s the perfect occasion to host a casual pizza night, order from a favorite local pizzeria, or let everyone create their own personalized pie. Add a few sides, fun drinks, and plenty of conversation, and you have an easygoing celebration that brings people together—one slice at a time.

National Pizza Party Day is observed annually on the **third Friday of May**. It is a modern food observance centered on sharing pizza in a social setting, rather than on commemorating a single historical event, restaurant, or inventor. Public listings of food-related observances, including the *List of food days*, identify the third Friday of May as the date, but do not provide a definitive account of the day’s founder or exact year of establishment. As a result, claims assigning its creation to a particular person or business should be treated cautiously.

The observance draws on the much older history of pizza itself. Flatbreads topped with other ingredients have existed in various forms for centuries, while the modern pizza tradition developed especially in Naples, Italy, where inexpensive breads topped with ingredients such as tomatoes, cheese, and oil became associated with everyday urban life. Pizza later spread internationally through migration, restaurants, frozen-food production, and delivery services. In the United States and elsewhere, it became strongly linked with informal gatherings, celebrations, school events, and group meals—conditions that provide the cultural foundation for a “pizza party” observance.

Over time, National Pizza Party Day has functioned primarily as a promotional and social occasion. Pizzerias, food brands, workplaces, schools, families, and friends may mark the third Friday of May by ordering or preparing pizza and emphasizing communal participation. Its significance lies less in formal ceremony than in the way it reflects pizza’s transformation from a regional Italian food into a widely shared international comfort food. The day also highlights the social meaning of eating together: pizza is easily divided, customized, and served to groups, making it particularly suited to casual celebrations.

Because the observance has no universally documented founding narrative, its history is best understood as part of the broader growth of food-themed calendar days during the modern era. These observances often gain recognition through calendars, media coverage, restaurants, and social-media participation rather than through official government designation. National Pizza Party Day therefore represents a contemporary celebration of pizza’s communal appeal, observed each year on the **third Friday of May**.
