Joseph Astbury Warbrick (1 January 1862 – 30 August 1903) was a Māori rugby union player who represented New Zealand on their 1884 tour to Australia and later captained the 1888–89 New Zealand Native football team that embarked on a 107-match tour of New Zealand, Australia, and the British Isles. Warbrick effectively retired from rugby after returning from the tour, with the exception of an appearance for Auckland in 1894, and went on to work as a farmer and tourist guide in the Bay of Plenty. In 1903, he was killed along with several others by an eruption of the Waimangu Geyser.
