Tupí, also known as formatge de tupí, is a fermented cheese of a certain area of the Pyrenees and Pre-Pyrenees made from cows' or sheep's milk.

It is a cheese traditionally prepared in the mountainous Pallars region, as well as in the Cerdanya and the Alt Urgell. Together with the llenguat, another fermented cheese of the same area, it is one of the few varieties of cheese of true Catalan origin.
