Tuesday, March 14, 2024, is mathematicians' favorite holiday: Pi Day! The annual holiday is devoted to the one and only: π. Sure, pi is 3.14, a mathematical constant, never-ending and the circumference-to-diameter ratio of a circle — you know the drill. But it is also the perfect excuse to indulge in your favorite pie, thanks to the restaurants and bakeries who celebrate by offering deals, discounts and freebies.

Whether you prefer pizza pie or dessert pies (or a slice of both), you'll likely be able to find a deal that will satisfy your craving — and save you some cash. This year, we're seeing fun deals from our favorite pizza joints like Pizza Hut, Papa John's and Blaze Pizza, including pizzas for $3.14 and less. The same goes for dessert pies — plenty of bakeries offer discounts on their customer-loved pies at Goldbelly today. Don't mind if we do!

Continue on to find the best Pi Day deals of 2024, whether you're in the mood for a slice of cheese pizza or Florida Key lime pie.
