Tree-class trawlers were a class of anti-submarine naval trawlers 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.
