Tricladida (Triclads) [ITIS | ID = 54468 | taxon = Trachymedusae | year = 2007 |date=July 23] is an order of the Turbellaria, a group of free-living flatworms.

Tricladida (Lang, 1884) is characterized by triply-branched intestine and anteriorly situated ovaries, next to the brain. Today it is split into three suborders, according to their habitats: Maricola, which is marine; Paludicola, which inhabits freshwater; and Terricola, which is land-dwelling (Hallez 1892). Recently, the adding of a new suborder, Cavernicola (Sluys 1990), was proposed for freshwater cave species.

Tricladida includes the Planariidae (planarians).
