Manawatu Rugby Union

The Manawatu Rugby Football Union (MRU) is the governing body of the sport of rugby union in the Manawatū-Whanganui region of New Zealand.

Founded in 1886, Manawatu is one of New Zealand's oldest rugby unions. In 1892, the MRU, amongst other unions, was instrumental in the founding of the New Zealand Rugby Union (NZRU). In 1997–1998 Manawatu entered into an amalgamation with Hawke's Bay, as the "Central Vikings", and wore orange and blue.

The union is based in the city of Palmerston North though its catchment area includes players and clubs from nearby towns in the province, including Ashhurst, Feilding, Rongotea, Linton, Bulls, Pahiatua, Woodville and Dannevirke. It has over 5,000 players, making it the tenth largest union in New Zealand in terms of player numbers. In 2011, the union celebrated its 125th jubilee.

Manawatu have traditionally played in a distinctive green and white tramline jersey, which is thought to have been established in 1909. In 1996, a jersey including red was worn, and colours worn have varied since the union was formed.

The union's home ground is Central Energy Trust Arena.
