The Colchester Reef Light is an active lighthouse situated on Colchester Reef in the Western Basin of Lake Erie south of the town of Colchester, Ontario. It was originally built in 1885 by Colonel William P. Anderson to replace a lightvessel that was previously stationed on that location. The original lighthouse tower was demolished in 1954 and the current structure is a white steel skeletal tower with a helicopter landing pad. It is currently listed on the Canadian List of Lights as Light No. 620 and can be found on the Canadian Hydrographic Service Chart No. 2123.
