Millswood is an inner-southern suburb of Adelaide in the City of Unley. It is dissected by Goodwood Road, which travels north to the Adelaide central business district from the southern suburb of Pasadena. Millswood also had its own railway station along the Goodwood-Belair line, but this was closed in 1995. Goodwood Road passes under the railway line in a deep underpass which may flood during heavy rain.
