埃里思（Erith）是英国伦敦的一个地区，在行政区划上属于贝克斯利伦敦自治市。埃里思邻近泰晤士河。在1961年之后，埃里思开始快速城市化。现在埃里思拥有伦敦最长的码头。

Erith (/ˈɪərᵻθ/) is a district of the London Borough of Bexley in south-east London, England, next to the River Thames, north-east of Bexleyheath and north-west of Dartford. Erith town centre has undergone modernisation and an increase in dwellings since 1961. The curved riverside high street contains three listed buildings, including the Church of England church and the Carnegie Building, while the district otherwise consists primarily of suburban homes. Erith is linked to central London and Kent by rail and a dual carriageway. It has the longest pier in London, and retains a coastal environment with salt marshes as well as industrial land.
