Captain Gilbert Mair NZC (10 January 1843 – 29 November 1923) was a New Zealand surveyor, interpreter, soldier and public servant.

He was born in Whangārei, Northland, New Zealand on 10 January 1843, the son of an early trader, also named Gilbert Mair.

He took part in the Invasion of Waikato against the Kingitanga forces, and became famous in late 1863 for entering into discussions with the rebels during the Battle of Orakau under a flag of truce.

[3] In July 1871 Ropata Wahawaha, Tom Porter and Ngati Porou warriors were joined by Mair and Captain George Preece leading a taua (war party) of Arawa.

The next day they found a camp with a fire still burning and then spotted a group of people climbing the cliff on the opposite side of the flooded stream.

In the 1880s Mair was the government officer trusted with establishing friendly relationships with Rewi Maniapoto in order to facilitate the main trunk railway to enter the King Country.

The couple had two children, John Gilbert and Kathleen Irene, who became a noted artist under her married name as Airini Vane.
