Bursaria tenuifolia is a species of flowering plant in the family Pittosporaceae and is endemic to north-eastern Queensland. It is a shrub or spindly tree with elliptic to rhombic adult leaves, spiny foliage when young, flowers with five whitish petals, and slightly flattened, papery fruit.

Description
Bursaria tenuifolia is a shrub or spindly tree that typically grows to a height of up to 20 m and has smooth, mottled bark. The young growth is armed with spines, the edges of leaves with teeth or lobes. Adult stages have few spines, the leaves elliptic to more or less rhombic, 40–80 mm long and 10–22 mm wide on a petiole 4–14 mm long. There are both andromonoecious and bisexual flowers, the bisexual flowers on pedicels 6–8 mm long. The sepals are 1–2 mm long and spread from the base and the five petals are white, 4–6 mm long and also spread from the base. Flowering mostly occurs from April to July and the fruit is a slightly flattened, papery capsule 6–8 mm long and wide.

Taxonomy
Bursaria tenuifolia was first formally described in 1899 by Frederick Manson Bailey in his book The Queensland Flora. The specific epithet (tenuifolia) means "narrow-leaved".

Distribution and habitat
This bursaria grows in open scrubland and in the margins of rainforest at altitudes up to about 1000 m and occurs in north-eastern Queensland.
