Middle Park, between the suburbs of Albert Park and St Kilda, is 5 km south of central Melbourne. Its southern border is the Port Philip Bay and the northern border is the Albert Park parkland.
In 1857 a railway line was opened between Melbourne and St Kilda, running along high ground to the south of the Albert Park lagoon. There was also a linear lagoon on the other side of the railway, occupying about a quarter of the area of Middle Park. Most of Middle Park is not more than 4 metres above sea level.
