Ilex montana (Mountain Winterberry; also "Mountain Holly" which is more typically Ilex mucronata) is a species of holly native to the United States, ranging along the Appalachian Mountains from southeast Massachusetts to northeast Alabama and northern Georgia. Synonyms include Ilex monticola.
It is a deciduous shrub or small tree growing to 9–12 m tall. The leaves are 3-9 cm long and 2-5 cm broad, light green, ovate or oblong, wedge-shaped or rounded at the base and acute at apex, with a serrated margin and an acuminate apex; they do not suggest the popular idea of a holly, with no spines or bristles. The leaves turn yellow before dropping in late autumn. The flowers are 4–5 mm diameter, with a four-lobed white corolla, appearing in late spring when the leaves are more than half grown. The fruit is a spherical bright red drupe 8-10 mm diameter, containing four seeds.
It is treated by some botanists as a variety of the related Ilex ambigua (Sand Holly), as I. ambigua var. monticola; the two are sometimes mistaken for each other in the U.S. southeastern coastal plain.
