Quercus lyrata, the overcup oak, is an oak in the white oak group (Quercus sect. Quercus). It is native to lowland wetlands in the eastern and south-central United States, in all the coastal states from New Jersey to Texas, inland as far as Oklahoma, Missouri, and Illinois. There are historical reports of it growing in Iowa, but the species appears to have been extirpated there.
The leaves are 10–16 cm (4–6 1⁄4 in) long, or rarely to 20 cm (7 3⁄4 in), and 5–10 cm (2–4 in) broad, deeply lobed, often somewhat lyre-shaped (lyrate), dark green above, paler and often finely hairy beneath.
The wood is valuable, similar to that of other white oaks, and used for the same purposes.
