Trinity Buoy Wharf is the site of a lighthouse, by the confluence of the River Thames and Bow Creek on the Leamouth Peninsula, Poplar.

The site was used as a maintenance depot, and storage facility for the many buoys that aided navigation on the Thames; and the wharf for docking and repair of lightships.

The lantern at the top of the tower came from the Paris Exposition of 1867, where Trinity House had used it to demonstrate Professor Holmes's improved system of electric lighting for lighthouses.

[4] In December 1988, Trinity House closed the wharf, and the area was acquired by the London Docklands Development Corporation.

In 1998, the LDDC set up the Trinity Buoy Wharf Trust with a 125-year lease to hold the land for the people of London.

In 2016 Trinity Buoy Wharf Trust acquired two historic tugboats, the Knocker White and the Varlet from the Museum of London Docklands.
