Aston Wyatt Greathead (31 May 1921 – 18 July 2012) was a New Zealand artist. He was born in Napier, the second of the five children of William John Edwin Greathead and Jane Greathead (née Wyatt), but the family soon moved to Timaru. Aston Greathead attended , where his drawings on the covers and page margins of his textbooks were sought-after by fellow pupils at the school's annual book sales. He never received art lessons, but was completely self-taught, developing his own natural talent from an early age. At one early art competition, the judges did not believe the work he submitted was his own, so he was locked in a room with a pencil and paper only to produce a work that amazed the judges.
