What Is the Tallest Tree in Pennsylvania?

In Pennsylvania, the tallest known tree is a towering tuliptree (Liriodendron tulipifera) located in the Susquehanna River watershed. This native hardwood has been measured at over 150 feet in total height, with a substantial trunk circumference and a crown spread that together illustrate the species’ potential for scale in the state’s mixed hardwood forests. While individual red oaks and eastern white pines approach considerable heights, documented tuliptrees remain the most consistently tall. This profile outlines the species, location context, measurement criteria, and conservation status of Pennsylvania’s record tree.
