'''Tree-class trawlers''' were a class of [[anti-submarine warfare|anti-submarine]] [[naval trawler]]s which served in the [[Royal Navy during the Second World War]]. They were nearly identical to the {{sclass2|Isles|trawler|3|naval}}s, 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.<ref>Antony Preston (ed.), ''Jane's Fighting Ships of World War II'', p. 78. New York: Military Press, 1989. This is largely a reprint of ''Jane's Fighting Ships 1946-47'' with materials from some earlier editions.</ref> Both were sold in 1948.
