Rangitīkei (before 2008 spelled Rangitikei without a macron) is a New Zealand parliamentary electorate, returning one Member of Parliament to the New Zealand House of Representatives. The current MP for Rangitīkei is Suze Redmayne of the National Party.^[1] She has held this position since 2023.

The electorate has existed continuously since the 1861 general election.

Rangitīkei is the third largest general electorate by area in the North Island. It encircles, but does not include, Palmerston North. The electorate straddles State Highway 1 through Bulls, Marton, Taihape, and Waiouru as far as Mount Ruapehu Its largest centre is Feilding. Its western boundary, from south of Whanganui, extends northwards to include the communities of Ohakune, National Park, and Taumarunui. At the 2014 boundary review, the population of the RangitĪkei electorate was below tolerance and projected to decline further, so the Representation Commission shifted population around Shannon from Ōtaki into RangitĪkei.^[2]

Between Census 2006 and Census 2013 the RangitĪkei electorate experienced a 0.4% decline in population in comparison to a 5.3% increase in New Zealand as a whole. One in ten (10.0%) stated their highest qualification as a Level 2 certificate, the fourth-largest share among general electorates. One in ten (10.4%) also listed their occupation as a community and personal service worker, the fifth-largest percentage. Six industries accounted for close to two-thirds (61.3%) of those working in 2013: agriculture, forestry, and fishing (16.8%); manufacturing (9.3%); education and training (9.0%); public administration (8.9%); health care and social assistance (8.9%); and retail trade (8.4%).^[2]

A seat named Wanganui and Rangitikei was contested at the very first general election in New Zealand in 1853. The use of an electorate named Rangitikei in its own right dates from the third session of the New Zealand Parliament. In a somewhat auspicious start for the seat, the first Member of Parliament for the seat in 1861 was future Prime Minister William Fox. Fox resigned twice; first on 16 May 1865, causing the 1865 by-election (won by Robert Pharazyn), and then on 11 March 1875, causing the 1875 by-election (won by John Ballance).^[3]

Three members died while holding the seat: Douglas Hastings Macarthur died on 24 May 1892 and was succeeded by John Stevens; Arthur Remington died on 17 August 1909 and was succeeded by Robert Smith; and Sir Roy Jack died on 24 December 1977 and was succeeded by Bruce Beetham.

The current boundaries of the seat date from the introduction of mixed-member proportional (MMP) voting in 1996. The seat was created by adding the southern tip of King Country to the northern tip of the Manawatu seat, and drafting in the towns to the east of Whanganui from Waitotara. The rural conservative nature of the seat makes it a safe National seat, though for six years in the 1970s and 80s it was held by a third party MP, Social Credit leader Bruce Beetham.
