The Lefevre Peninsula is a peninsula located in the Australian state of South Australia located about 15 kilometres (9.3 mi) northwest of the Adelaide city centre. It is a narrow sand spit[5] of about 30 square kilometres (12 sq mi) running north from its connection to the mainland.
The name given to the peninsula by the traditional owners of the area, the Kaurna people, was Mudlangga, meaning "nose-place" in the Kaurna language.
