Luna Park Glenelg was an amusement park that operated at Glenelg, South Australia from 1930 until 1935. Plans for an amusement park at the seaside town were first raised in 1928, but not acted upon. In 1929, a lease to build a scenic railway at Colley Reserve was granted by the Glenelg Town Council. This lease was expanded in 1930 to include other rides and attractions, and Luna Park Glenelg opened on 8 October 1930.

Glenelg is a beach-side suburb of the South Australian capital of Adelaide. Located on the shore of Holdfast Bay in Gulf St Vincent, it has become a tourist destination due to its beach and many attractions, home to several hotels and dozens of restaurants.
