Salthouse Dock is a dock on the River Mersey, England, and part of the Port of Liverpool. It is situated in the southern dock system, connected to Canning Dock to the north, Wapping Dock via Wapping Basin to the south and Albert Dock to the west.

Designed by Thomas Steers and being built from 1734,^[4] Salthouse Dock was completed after his death by Henry Berry, opening in 1753.^[5] The dock was originally known as South Dock, the name changing because it was nearby to John Blackburne's saltworks.^[6][7] As is indicative of its name, the dock was an important transit terminal for the salt industry.^[8] Liverpool was a base for the refining of rock salt from Cheshire and its onward transportation. The dock also handled agricultural produce from Ireland and the Mediterranean.^[5] Around 1769, John Okill had a shipyard on the south side.^{[9][better source needed]}

Structural improvements were made to the dock basin in 1842 and 1855.^[10] The opening of the Albert Dock in 1846 allowed vessels to be unloaded there, before moving on to the Salthouse Dock for loading.^[10] By the mid-19th century, the main trade from the dock was with China and the East Indies.^[6] The dock served square rigged sailing ships until about 1914.^[6]

Custom House railway station, on the Liverpool Overhead Railway, was opened at the north-east corner of the dock in 1893.^[11][12] The station, opened at the same time as the railway, was renamed Canning in 1947 and closed in 1956 along with the railway.^[11][13] By 1920, the Wapping and Salthouse Goods Depot of the Lancashire and Yorkshire Railway was on the eastern side of the dock.^[14]

A Royal Navy training ship, HMS Eagle, was based at Salthouse Dock from the end of the 19th century.^[6] This was originally a wooden vessel, which was renamed HMS Eaglet in 1918 and replaced in 1927.^[6] The following vessel survived until 1972.^[6] In 1934, the dock had warehousing along all four quays.^[12] The dock closed in 1972.^[5]

Salthouse Dock is the oldest existing dock in Liverpool, and some of the masonry in the south-west corner of the dock is from the original construction.^[20] The dock walls are Grade II listed.^[16] A granite stone gable and arch entrance survives at the south east corner of the dock, from a transit shed built by Jesse Hartley.^[5][10]

Following the completion of the Liverpool Canal Link in 2009, Salthouse Dock is on the route of the Leeds and Liverpool Canal extension to Liverpool Marina at Brunswick and Coburg Docks. The waterspace of this and the other docks in the southern system was owned by British Waterways from 2003 to 2012, now transferred to the Canal & River Trust.^[1] Salthouse Dock has pontoon moorings for small watercraft.^[21][22]
