Mount Roskill is a volcanic peak and suburban area in the city of Auckland, New Zealand.

The peak, which is to the southwest end of the suburb, is 110 metres in height, and is one of the many extinct cones which do the inner city of Auckland, all of which are part of the Auckland Volcanic Field.

The suburb is located seven kilometres to the south of the city centre, and is surrounded by the neighbouring suburbs of Three Kings, Sandringham, Wesley, and Hillsborough. One of the city's larger and more historic suburbs, it was a borough from 1947 until local government reorganisation in 1989.
