Ras超家族（英語：Ras superfamily）是一个小GTP酶（英语：small GTPase）蛋白质超家族，名称来自其中的Ras亚家族（在人类中为KRAS、NRAS和HRAS）。

Ras超家族中有超过100种蛋白质^[1] ，根据其序列、结构和功能，可分为9个主要的家族，各自还可再分亚家族。这9个蛋白质家族为：Ras、Rad、Rab、Rap、Ran、Rho、Rheb、Rit和Arf，Miro最近也被列入这个超家族中。

每个亚家族都有共同的G结构域核心，提供GTP酶与GTP/GDP交换活性。

周围序列有助于确定小GTP酶的功能特异性，例如Rho亚家族常见的“插入环”，特别有助于与效应蛋白如IQGAP和WASP(Wiskott–Aldrich syndrome protein)结合。

通常，Ras家族负责细胞增殖：Rho用于细胞形态，Ran用于核运输，Rab和Arf用于囊泡运输^[2]。
