Euonymus americanus is a species of flowering plant in the family Celastraceae. Common names include strawberry bush, American strawberry bush, bursting-heart, hearts-a-bustin, and hearts-bustin'-with-love. It is native to the eastern United States, its distribution extending as far west as Texas. It has also been recorded in Ontario.

This is a deciduous shrub growing up to 2 metres (6 ft 7 in) tall. The oppositely arranged leaves are leathery or papery in texture and measure up to 10 cm (3.9 in) long. Flowers are borne in the leaf axils on peduncles up to 2.2 cm (0.87 in) long. The yellow-green sepals are 1 or 2 cm (0.39 or 0.79 in) long and the greenish or reddish petals above are smaller. The fruit capsule is about 1.5 cm (0.59 in) wide with a red warty or spiny covering. The capsule splits into five sections, revealing seeds covered in bright red arils.

The seeds are dispersed by animals. Deer have been known to graze on this plant and seem to love the tender leaves and stems. Humans should take the red color of the seeds as a warning; they are known to be a strong laxative and cause severe diarrhea. In fact, this genus of plants in general is considered poisonous to humans.
