In Greek mythology, Thoosa (, ), also spelled Thoösa, was, according to Homer, the sea nymph daughter of the primordial sea god Phorcys. By Poseidon, she is the mother of the Cyclops Polyphemus.Homer, Odyssey 1.70–73. Heubeck, Hainsworth and West, p. 69 on line 71-3, notes that "Thoosa seems to be an ad hoc invention, her name recalling the swift movement of the waves".; compare with Apollodorus, E.7.4; Nonnus, 39.293-294; Servius' Commentary on Virgil, Aeneid 5.824; Theocritus, Idylls 11.25 ff. & 62ff.
