The Ruahine Range (often referred to as the Ruahine Ranges) is one of several mountain ranges in the North Island of New Zealand which form a ridge running parallel with the east coast of the island between East Cape and Wellington.

The ridge is at its most pronounced in the southern part of the island, where it is comprised of the Rimutaka, Tararua, and Ruahine Ranges.

The Ruahines run northeast-southwest for 110 kilometres from inland Hawke's Bay to near Woodville. It is separated in the south from the northern end of the Tararua Range by the Manawatu Gorge.

The highest peak in the Ruahines is Mount Mangaweka, at 1730 metres.
