Petwood railway station was a ground-level stopping place located on the Adelaide to Wolseley line serving the South Australian locality of Petwood.
The line opened in stages: on 14 March 1883 from Adelaide to Aldgate, on 28 November 1883 to Nairne, on 1 May 1886 to Bordertown and on 19 January 1887 to Serviceton.
The station was still listed as a stopping place in the ANR public timetable in July 1976, though the station sign was removed during the crossing loop extension in 1980, suggesting that it was closed by this time.
There is no longer any trace of the station, though the 1052m crossing loop was retained during conversion to SG.
