The Terfeziaceae, or desert truffles, is a family of truffles (Berber languages: Tirfas, Arabic: كمأ, romanizedKam', Turkish: Domalan, Kurdish: دۆمبەڵان, romanizedDombelan, Hebrew: כמהת הנגב, romanizedkmehat hanegev). The group consists of three genera: Terfezia, Tirmania, and Mattirolomyces. They are a few centimetres across and weigh from 30 to 300 grams (1–10 oz).

The family is endemic to arid and semi-arid areas of the Mediterranean Region, North Africa, and the Middle East, where its members live in ectomycorrhizal association with Helianthemum species and other ectomycorrhizal plants (including Cistus, oaks, and pines). Desert truffles are often used as a culinary ingredient.
