Challis railway station (officially Challis Station) is a suburban railway station in Kelmscott, a suburb of Perth, Western Australia. It is on the Armadale line which is part of the Transperth network, and is southwest of Perth station and north of Armadale station. The station opened on 29 October 1973, as did the adjacent Sherwood station, filling the large gap between Armadale station and Kelmscott station. It consists of two side platforms with a pedestrian level crossing. It is not fully accessible due to steep ramps and wide gaps at the pedestrian level crossing. Services are operated by Transperth Train Operations, a division of the state government's Public Transport Authority.

The station is one of the least used ones on the Transperth network, with just 259 boardings per day in October 2017. The City of Armadale rezoned nearby land in the 2010s with the goal of increasing patronage. Description Challis station is along the South Western Railway, which links Perth to Bunbury.
