盘菌科（英文：Pezizaceae、cup fungi）是真菌下的一个科。2008年的数据统计，其下共有31属和230种。

The Pezizaceae (commonly referred to as cup fungi) are a family of fungi in the Ascomycota which produce mushrooms that tends to grow in the shape of a "cup". Spores are formed on the inner surface of the fruit body (mushroom). The cup shape typically serves to focus raindrops into splashing spores out of the cup. Additionally, the curvature enables wind currents to blow the spores out in a different manner than in most agarics and boletes.
