Gwalior House is the former residence of the Maharaja of Gwalior in Delhi. It is located at Rajpur Road in Civil Lines, Delhi.
The house has been involved in an inheritance feud within the princely family. It is of modest size and can therefore not be considered a palace.
Since Gwalior was a 21-gun salute princely state, a large plot was set aside next to the Kingsway, today Rajpath, for a palace to be constructed next to the Baroda House and Patiala House (at 28.6166°N 77.2326°E / 28.6166; 77.2326). However the princely family refused to be aligned in this city planning scheme by the British. The plot stood empty and was temporary used as the Prince's Park Mess.
