Populus grandidentata (Large-toothed Aspen) of the Salicaceae (Willow Family) is also called bigtooth aspen, poplar or popple.

The medium to large-sized tree (18 - 24 m (60 - 80 ft) high), is a broadleaved hardwood.

The crown is loose, open and irregular, with spreading branches.

The alternate, suboricular leaves are 5 - 7.5 cm (2 - 3 in) long, and coarsely dentate with a flattened petiole. Young leaves have a whitish tomentose.

This tree can generally be found in southern Ontario east to the Maritime provices, south to Virginia, west to Ohio and eastern Iowa in dry/fresh, sandy and coarse loamy soil conditions. Large-toothed aspen is found in pure aspen forest covers either singly or in various combinations with trembling aspen and balsam poplar. In the overstory it is sometimes found in mixed association with trembling aspen, red pine and white pine.
