The Whitecliffs Branch was an 18.4 kilometres (11.4 mi) long branch line railway that formed part of New Zealand's national rail network in the Canterbury region of the South Island. It was more industrial than the many rural branches on the South Island's east coast whose traffic primarily derived from agriculture, and it operated from 1875 until 1962.

Whitecliffs is a village located in the Selwyn District of the Canterbury region of New Zealand's South Island. It has also been known as South Malvern, and the name of Whitecliffs comes from terrace cliffs above the Selwyn River / Waikirikiri.
