Patriarca, Ancient tree in Vassununga State Park, Brazil.

Patriarca is a jequitibá-rosa (Cariniana legalis) in Vassununga State Park, in Santa Rita do Passa Quatro, São Paulo state. It stands 40 metres tall, with a trunk 3.6 metres in diameter and 11.3 metres in circumference, and its roots reach 18 metres deep. Its calculated gross weight is 264 tonnes.

This jequitiba-rosa tree originated around 1437 and ranks among the oldest living organisms in the Brazilian Atlantic Forest region. Its age connects the history of the forest with the long human settlement of the region.

Local communities used the bark of jequitiba-rosa trees like this one for medicinal remedies and craft materials.

The Patriarca stands in the Cerrado sector of Vassununga State Park, reached on foot along the park's trails; the tree is roughly 40 m tall and its trunk about 11.3 m around, so allow time to walk the final stretch. Bring water and wear closed shoes, since the paths cross open cerrado vegetation.

The tree's age has been estimated at over three millennia in earlier studies, while carbon measurements by Mário Tomazello Filho, head of the growth-ring laboratory at ESALQ, place its birth between 600 and 900 years ago, before the Portuguese arrived in Brazil.
