Islands in the River Thames

This article lists the islands in the River Thames, or at the mouth of a tributary (marked †), in England.

A small minority of list entries are referred to as Island, Ait or Eyot and are vestiges, separated by a depression in the land or high-water-level gully.

Most are natural; others were created by excavation of an additional or replacement navigation channel, such as to provide a shorter route, a cut.

Many result from accumulation of gravel, silt, wildfowl dung and plant decay and root strengthening, particularly from willows and other large trees.

As the Jubilee River is maintained with flow at all times,[citation needed] they may be coming to be accepted by publications as on an island of the Thames, reflecting their objective strict geographical status.
