Desmarestiales is an order in the brown algae (Phaeophyceae). Members of this order have terete or ligulate (flat) pinnately branched thalli attached by discoid holdfasts. They have a sporphytic thallus usually aggregated to form a pseudo-parenchyma.[1] The order gets its name from the genus Desmarestia, which is named after the French zoologist Anselme Gaëtan Desmarest (1784–1838).[2][3]

As the general name of the class suggests, their pigmentation is brown.
