HMS Ambrose was a steamship that was built for in 1903 as a passenger liner. The Booth Steam Ship Company ran her scheduled on services between Liverpool and Brazil until the First World War.

Ambrose was converted into a Royal Navy armed merchant cruiser (AMC) in 1914–15 and then into a submarine depot ship in 1917. After the First World War she supported Royal Navy submarines in the Far East from 1919 until 1928, when she was laid up in the Reserve Fleet.

In 1938 Ambrose was renamed HMS Cochrane and converted into a destroyer depot ship. Cochrane survived the Second World War and was scrapped in 1946.
