Pleioluma is a genus of flowering plants in the family Sapotaceae. It includes 40 species of evergreen hermaphroditic or gynodioecious trees, reaching up to 25 meters tall.

The genus ranges from the Nicobar Islands through Thailand, Malaysia, Indonesia, and the Philippines to New Guinea, the Bismarck Archipelago, Solomon Islands, New Caledonia, and Australia (Queensland, Northern Territory, and New South Wales). At least 15 species are native to New Guinea.

The genus was described in 1961 by Charles Baehni. In 2013 Swenson et al. enlarged the genus to include the genus Beccariella and some species formerly classed in Planchonella and Pouteria, based on a phylogenetic analysis.
