Leanderthal Lady is the skeletal remains of a prehistoric woman discovered in January 1983 by the Texas Department of Transportation at the Wilson-Leonard Brushy Creek Site (an ancient Native American campsite) in the city of Cedar Park, Texas, a suburb of Austin, the state capital. The remains were also alternatively labeled "Leanne". Both names were inspired by the proximity of the site to the town of Leander, to the north.
Carbon dating and stratigraphic analysis showed the remains to be 10,000 to 13,000 years old. The skeleton is of a 5-foot-3-inch (1.60 m) tall female who was approximately eighteen to thirty years old at the time of death. The find was significant as one of the oldest and most complete human skeleton finds in North America.
