Sir Geoffrey Winston Russell Palmer is a New Zealand lawyer, legal academic, and former politician, who was a member of Parliament from 1979 to 1990. He served as the 33rd prime minister of New Zealand for a little over a year, from August 1989 until September 1990, leading the Fourth Labour Government. As minister of justice from 1984 to 1989, Palmer was responsible for considerable reforms of the country's legal and constitutional framework, such as the creation of the Constitution Act 1986, New Zealand Bill of Rights, Imperial Laws Application Act, and the State Sector Act. He served as president of the New Zealand Law Commission, from 2005 to 2010.

The Fourth Labour Government of New Zealand governed New Zealand from 26 July 1984 to 2 November 1990. It was the first Labour government to win a second consecutive term since the First Labour Government of 1935 to 1949. The policy agenda of the Fourth Labour Government differed significantly from that of previous Labour governments: it enacted major social reforms and economic reforms.
