Hannans is a residential suburb of Kalgoorlie–Boulder, a city in the Eastern Goldfields region of Western Australia.

Hannans contains Kalgoorlie–Boulder's northernmost dwellings, which are located around 4 kilometres (2.5 mi) from the Kalgoorlie town centre.

The suburb is roughly diamond-shaped, with large areas of uncleared bushland in the north and east.

Hannans is bounded by the Leonora branch line of Eastern Goldfields Railway to the north-east; by Killarney Street to the south-east; by a series of minor roads to the south-west; and to the north-west by a line running parallel to a track leading back to the railway.

[5] Most of the suburb's north is occupied by the Karlkurla Bushland Park, which was created in 2000 and contains 200 hectares (490 acres) of native fauna designed to mimic the pre-mining environment.
