Pittosporum lancifolium, known as the Narrow-leaved Orange Thorn or Sticky Orange Thorn, is a shrub or tree growing in eastern Australia. Often found at altitudes above 500 metres above sea level; from Mallanganee National Park in New South Wales in the south to Yarraman in south east Queensland in the north. Usually found in association with the Hoop Pine on the drier types of rainforest on soils enriched by basalt. The specific epithet lancifolium refers to the lance shaped leaves.
