Editing Quercus palustris (section)

=== Associated species ===
Due to similarity in leaf shape, the pin oak is often confused with [[scarlet oak]] and [[Quercus velutina|black oak]], and occasionally, [[Quercus rubra|red oak]]. However, it can be distinguished by its distinctive dead branches on the lower trunk ("pins"), and its uniquely shaped crown. The sinuses on pin oak leaves are also deeply cut, often covering just as much area as the leaf itself.

The pin oak is the only known food plant of ''[[Bucculatrix domicola]]'' caterpillars.
