The Onehunga Branch is a railway line in Auckland, New Zealand. It was constructed by the Auckland Provincial Government and opened from Penrose to Onehunga on 24 December 1873, and extended to Onehunga Wharf on 28 November 1878.

It was previously closed to passenger traffic on 19 January 1973, and mothballed in 2007. The section from Penrose to Onehunga was reopened on 18 September 2010, with regular passenger services beginning on 19 September 2010. It is 3.31 kilometres (2.06 mi) in length.

Onehunga Line services run on the branch. Because it is single-track only, only one passenger train at a time is permitted, except in emergencies.
