Harpullia is a genus of 37 species of small to medium-sized trees in the soapberry family Sapindaceae. They have a wide distribution ranging from India eastwards into the Pacific Ocean. They are usually found in or on the margins of rainforests.
The eight species of Australian Harpullia are known as tulipwoods and were prized for their dark coloured timber. The one most commonly known to horticulture is H. pendula which is widely planted as a street tree along the east coast of Australia.
