Otter Dock was a branch of the Grand Union Canal between Yiewsley and West Drayton in Middlesex (London, England). It was cut during the years 1876 to 1879 to service Yiewsley's brickworks. Bricks were moulded and fired in the local brickfields and transported by canal to a yard near South Wharf Basin, Paddington. The last local brickfield at Starveal (Stockley Bridge area) disappeared in 1935 and soon after Otter Dock was filled in.
