The alpine river galaxias (Galaxias paucispondylus) is a galaxiid of the genus Galaxias, found only in mid to high elevation streams flowing from the Southern Alps of New Zealand. It grows to a length of up to 11 cm.
Alpine galaxias are speckled olive-green over a light brown base. The single large dorsal fin is rounded, and set back two thirds of the body length, the anal fin a little further back. The caudal fin is large and slightly forked. Like all galaxiids it lacks scales and has a thick, leathery skin covered with mucus.
They are non-diadromous and therefore do not have a marine phase and are not part of the whitebait catch.
