灰狐属（学名：Urocyon）是食肉目犬科犬亚科的一属，现存2种，即灰狐（Urocyon cinereoargenteus）和加州灰狐（Urocyon littoralis）。

The genus Urocyon (from the Greek word for "tailed dog") is a genus that contains two (or possibly three, see next paragraph) living Western Hemisphere foxes in the family Canidae; the gray fox (Urocyon cinereoargenteus) and the closely related island fox (Urocyon littoralis), which is a dwarf cousin of the gray fox; as well as one fossil species, Urocyon progressus.
