Parkside is an inner southern suburb of Adelaide, South Australia. It is located in the City of Unley.

The suburb was once home to the mental health campus of the Royal Adelaide Hospital. Known as 'The Parkside Asylum', it was the primary mental health facility in the state, and occupied approximately one-third of the suburb's area.

Parkside Post Office opened on 10 December 1859 and was renamed Eastwood in 1967.

Parkside lies on the southern boundary of the southern park lands. It is bounded, among others, by Glen Osmond, Greenhill, Unley and Fullarton roads.
