Outer Harbor is a suburb in the Australian state of South Australia located at the northern tip of the Lefevre Peninsula about 22 kilometres (14 mi) north-west of the Adelaide city centre.

The terminus of this line is the Outer Harbor station, situated next to the North Haven Golf Course and Overseas Passenger Terminal.

[citation needed] Until the 1970s Outer Harbor was a relatively isolated locality, separated from Largs Bay and Taperoo by several kilometres of sparsely occupied sand dunes and scrub.

[10] Much of the extreme northern end of Lefevre Peninsula leading to Outer Harbor remained sand dunes until a housing and marina development named North Haven commenced in the 1970s.

[12] Some light general aviation aircraft preparing to land at Parafield Airport pass over or near Outer Harbor.
