Castlemaine railway station is a regional railway station on the Deniliquin line, part of the Victorian railway network. It serves the north-western suburb and town of Castlemaine, in Victoria, Australia. Castlemaine station is a ground level unstaffed station, featuring two side platforms. It opened on 21 October 1862.

The station is also the termini of the Maldon and Moolort lines, but no passenger revenue services currently operates on the latter line, with the Victorian Goldfields Railway operating heritage services on the Maldon line.

Disused stations Elphinstone and Taradale are located between Castlemaine and Malmsbury, while disused stations Harcourt and Ravenswood are located between Castlemaine and Kangaroo Flat. Demolished station Chewton was also located between Castlemaine and Malmsbury.

In 1973, a turntable at the station was abolished. On 9 July 1977, the passenger service to Maryborough was withdrawn, and in 1978, a number of points were abolished, as was a crossover and the former carriage dock.

Rationalisation of the former yard occurred during the late 1980s. In 1989, signal boxes "A" and "B" were abolished, and replaced with a signal panel within the station office. Mechanical points were also abolished, and all signals were replaced with two and three position signals. Also in that year, boom barriers replaced interlocked gates at the Parker Street level crossing, located nearby in the down direction of the station.

On 17 December 2004, the Victorian Goldfields Railway was extended from Muckleford to Castlemaine. On 17 January 2005, the signal panel was abolished.
