The Tree class trawlers were a type of anti-submarine vessel which served in the Royal Navy during the Second World War. They were nearly identical to the Isles class trawlers, of which they are usually considered a subclass.

Six Tree class trawlers were lost during the war: Almond, Ash, Chestnut, Hickory, Juniper and Pine. One (Mangrove) was transferred to Portugal in 1943.

By the end of 1946, only Olive and Walnut remained in service with the Royal Navy. [2] Both were sold in 1948.
