The Encino Oak Tree, also known as the Lang Oak, was a 1,000-year-old California Live Oak tree, Quercus agrifolia, in the Encino section of Los Angeles, California. It was designated as a Los Angeles Historic-Cultural Monument (HCM #24) in 1963.
The Los Angeles Times once wrote of the Encino oak: "When the famed Lang oak tree of Encino was but a sapling, the Mayan Empire was crumbling and Vikings were sacking English sea towns." It was already 100 years old when Pope Urban II launched the first Crusade. And when the first Europeans passed through Encino in 1769 as part of the Portola Expedition, the tree was already more than 700 years old.
