Mizithra (Greek: μυζήθρα) is a traditional unpasteurized cheese made from sheep milk - and/or goat-milk whey with some added milk. The cheese is soft, snow-white, creamy, and granular; its flavor is similar to ricotta salata. It is made in various sizes and shapes, most commonly a truncated cone. The fresh, soft, sweet form is called simply mizithra; the sour version is xynomizithra. If it is aged, it becomes anthotyros. It is eaten as dessert with honey, or as mezes with olives and tomato. In the past, balls of Mizithra were hung outdoors in small sheets of muslin to air-dry.

In Cyprus a similar cheese is known in both types (fresh or dry) as "Anari" (Αναρή in Greek).
