Ternstroemia is a genus of flowering plants in the family Pentaphylacaceae. It is distributed in tropical and subtropical regions in Africa, Asia, and the Americas.

These are evergreen shrubs and trees. The leaves are alternately arranged, sometimes in clusters. Species are androdioecious, with some individuals bearing bisexual flowers and others with flowers that are functionally male. Flowers are solitary or borne in clusters. The flower has two bracteoles, five sepals, five petals, and many stamens. The berry-like fruit contains seeds that have red flesh over a thick endosperm. They are likely dispersed by birds.

T. gymnanthera is an Asian species cultivated as an ornamental plant. T. pringlei is one of the most widely used medicinal plants in Mexico.
