约克郡东瑞丁（英语：East Riding of Yorkshire），通称东约克郡，直译约克郡东瑞丁，英国英格兰约克郡-亨伯地区的名誉郡、非都市区（Non-metropolitan district）、单一管理区。行政总部位于贝弗利（Beverley），布德灵顿是第一大镇。

原文的「Riding」（瑞丁）是英联邦国家独有的地方行政单位，通常用于由3个次级行政区组成一个上级行政区的情况中─约克郡东瑞丁与相邻的约克郡北瑞丁、约克郡西瑞丁，曾是约克郡的3个构成部分。但由于幅原广阔，约克郡在1889年拆分成上述3个一级行政区，所以原文的「Riding」在1889年后已成为没有实际地方行政架构的概念。

The East Riding of Yorkshire, or simply East Yorkshire, is a ceremonial county of England. It is located in the region of Yorkshire and the Humber. It is a local government district with unitary authority status. For ceremonial purposes the county also includes the city of Kingston upon Hull, which is a separate unitary authority. It is named after the historic East Riding of Yorkshire (one of three ridings alongside the North Riding and West Riding), which also constituted a ceremonial and administrative county until 1974. From 1974 to 1996 the area of the modern East Riding of Yorkshire constituted the northern part of the non-metropolitan county of Humberside. At the 2011 Census the Unitary Authority population was 334,179.
