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.
In forests, the northern red oak grows straight and tall, to 28 m (90 ft), exceptionally to 43 m (140 ft) tall, with a trunk of up to 50-100 cm (20-40 in) diameter. Open-grown trees do not get so tall, but can develop a stouter trunk, up to 2 m (6 ft) in diameter. It has stout branches growing at right angles to the stem, forming a narrow round-topped head. It grows rapidly and is tolerant of many soils and varied situations, although it prefers the glacial drift and well-drained borders of streams. It is frequently a part of the canopy in an oak-heath forest, but generally not as important as some other oaks.
