Quercus rubra
（重定向自Quercus borealis）
Quercus rubra, commonly called northern red oak, or champion oak, (syn. Quercus borealis), is an oak in the red oak group (Quercus section Lobatae). It is a native of North America, in the eastern and central United States and southeast and south-central Canada. It grows from the north end of the Great Lakes, east to Nova Scotia, south as far as Georgia, Alabama, and Louisiana, and west to Oklahoma, Kansas, Nebraska, and Minnesota. It prefers good soil that is slightly acidic. Often simply called red oak, northern red oak is so named to distinguish it from southern red oak (Q. falcata), also known as the Spanish oak. It is also the state tree of New Jersey and the provincial tree of Prince Edward Island.
