The Aan River is a short river in the South Island of New Zealand.
The river flows out of Lake Innes and into the sea on the southern coast of the South Island.[1] [2] The river may be reached on foot via the South Coast Track, which crosses it via a suspension bridge.[3]
It also has a tributary that drains the basin to the south of the 1189-metre high Mount Aitkin.
