Pittosporum resiniferum, the resin cheesewood or petroleum nut, is a tree that grows in the Philippines and Malaysia, particularly in the wilderness surrounding the Mayon Volcano and in the Cordillera of the Philippines and Mount Kinabalu of Sabah, Malaysia. The petroleum nut derives its name from the resemblance of the fruit's odor to petroleum-based fuels. The fruits of the tree burn brightly when ignited, and can be used for illumination as torches or candles. Its fruit is also highly suitable for use in producing biofuel. This use has been encouraged by the Philippines Department of Agrarian Reform and the Philippine Coconut Authority.
