Peeni Ereatara Gladwyn Henare ([ˈpɛːni ˈhɛnaˌɾɛ]) is a New Zealand politician. He was a Labour Party member of parliament from the 2014 general election until 2026. He first held the Tāmaki Makaurau Māori electorate until being defeated by Te Pāti Māori's Takutai Tarsh Kemp in the 2023 general election, and then continued as a list MP until resigning from parliament in March 2026.

Henare is a great-grandson of Taurekareka Hēnare, who held the Northern Maori seat between 1914 and 1938. His grandfather was James Hēnare, who had stood for the National Party in five elections between 1946 and 1963. His father was Erima Henare, who was head of the Māori Language Commission, and his mother is Te Hemo Ata Henare, a master weaver. Henare's second cousin, Tau Henare (also a direct descendant of Taurekareka Hēnare) was a New Zealand Member of Parliament from 1993 to 1999 and from 2005 to 2014.

Henare's uncle was the Māori activist Dun Mihaka, and he has relations to both Shane Jones and Winston Peters.

Peeni Henare won the Tāmaki Makaurau electorate ahead of Rangi McLean of the Māori Party in 2014. In 2016, a member's bill submitted by Henare which aimed to ban the import of goods produced by slave labour was drawn from the ballot. The bill had been first introduced by Maryan Street and defeated at its first reading in 2009. It was again defeated at its first reading in 2016 due to opposition from the National Party and Act New Zealand.

During the 2017 New Zealand general election, Henare was re-elected in the Tāmaki Makaurau electorate, winning 9,396 votes. Henare was elected as a Minister outside Cabinet by the Labour Party caucus following Labour's formation of a coalition government with New Zealand First and the Greens in October 2017. He assumed the portfolio of Minister for Whānau Ora, which falls under the purview of Te Puni Kōkiri (the Ministry for Māori Development).

Following a cabinet reshuffle in late June 2019, Henare was appointed as Minister of Civil Defence.

During the 2020 general election, Henare retained Tāmaki Makaurau, defeating the Māori Party candidate and co-leader John Tamihere and Green co-leader Marama Davidson. When the official results were released, Henare had a majority of 956, but after the Māori Party requested a recount in Tāmaki Makaurau, Henare's majority fell slightly to 927. In November 2020, Henare was announced as Minister of Defence and Minister for Whānau Ora. He also assumed the health, housing and tourism associate portfolios with responsibility for Māori health and housing.

In May 2022 he indicated to Labour Party President Claire Szabó that he would possibly be unwilling to recontest Tāmaki Makaurau at the 2023 New Zealand general election, preferring instead to contest the election as a list-only candidate.
