Arthur Nelson Field (27 February 1882 – 3 January 1963) was a New Zealand journalist, writer and political activist.
There was a break during this period when he served as a Royal Navy sub-lieutenant and adjutant at Portsmouth, and on board RNV Spenser in the North Sea.
In 1909 he published The Citizen, an early far right publication which upheld motherhood, eugenics and monetary reform, and opposed "Maori Obstructionism" for seven years, 1912–1919.
During the Second World War, he was kept under surveillance by the Security Intelligence Bureau of New Zealand's Department of External Affairs.
In his later years, Field wrote a series of self-published tracts on his interpretations of economics, anti-socialist articles about the New Zealand Labour Party and trade union movement, and related matters.
