Poa triodioides, synonyms including Austrofestuca littoralis, is a species of flowering plant in the grass family Poaceae, native to southwestern and southeastern Australia and to New Zealand.

[1] The species was first described by Jacques Labillardière in 1805 as Festuca littoralis.

It was first transferred to Poa in 1864 by Joseph Dalton Hooker, but under the illegitimate name Poa littoralis,[1] which had already been used for a different species.

[6][7] A. littoralis was at one time the only species in the genus.

Austrofestuca has since been treated as a synonym of Poa.
