Lembophyllaceae is a family of pleurocarpous mosses in the order Hypnales. It was originally described by Finnish botanist Viktor Ferdinand Brotherus (1849–1929) in 1909. The family is mainly found in Australasia and southern South America.

Taxonomy Lembophyllaceae is closely related to the family Neckeraceae. Members of Lembophyllaceae are differentiated from Neckeraceae by their typically terete shoots (vs. mostly complanate), the leaves being mostly often loosely appressed, and frequently well-developed peristomes (vs. reduced or 'neckeroid' periostomes).
