'''''Elaeocarpus serratus''''', the '''Ceylon olive''', is a tropical [[flowering plant]] in the family [[Elaeocarpaceae]]. It is a medium to large tree, with white flowers. It has a disjunctive distribution, with the species occurring in Sri Lanka and southern India, and in Assam, Bangladesh and other parts in the north of the Indian subcontinent. The fruit is commonly eaten, and people also use the plant for ornamental, religious and folk-medicinal purposes. There are historical records of traditional-medicine use of the plant.

It natively occurs in the Sinharaja Forest Reserve, Sri Lanka,[4] and is found in various protected areas of Assam, including Nameri National Park, Dibru-Saikhowa National Park, Pakke Tiger Reserve and Hoollongapar Gibbon Sanctuary.[3]
The palm civet Paradoxurus jerdoni (Brown palm civet) consumes parts of the plant.[7]
The population in India is rapidly decreasing, partly due to over-exploitation of the plant (particularly for seeds), and partly due to habitat destruction.[3] It is cited as vulnerable in Arunachal Pradesh and Assam.
