Nonja (June 12, 1952 – December 29, 2007) was a female sumatran orangutan who was thought to be the oldest of her species in either the wild or captivity.

[1] Most orangutans die before they reach their mid-40s, which made Nonja unique and likely the oldest living orangutan in the world at the time.

[1] Nonja, whose name meant "girl" in Malaysian, was captured in the wild and brought to the Wassenaar Zoo in the Netherlands in 1955.

[1][2] Nonja died at the Miami MetroZoo on Saturday, December 29, 2007.

Experts believe that she died of either a brain tumor or an aneurysm.
