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 northeastern United States and southeast Canada. It grows from the north end of the Great Lakes, east to Nova Scotia, south as far as Georgia and states with good soil that is slightly acidic. Often simply called "red oak", northern red oak is formally 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.
