Grove Park Sidings is a large stabling complex for suburban commuter trains in Lewisham, South East London. It is situated approximately halfway between Hither Green Station and Grove Park station.

Grove Park Sidings were previously named Hither Green Sidings, until sidings closer to Hither Green were built and took that name, causing the site to be renamed Grove Park Sidings.

It consists of two sets of sidings, one on either side of the Main line which are linked by a pedestrian footbridge. On the Down side are Bramdean sidings and the large carriage shed, whilst on the Up side are St Mildreds sidings. There is also a carriage washing plant on the inlet road of Down sidings.
