Jacksonia chappilliae is a species of flowering plant in the family Fabaceae and is endemic to a restricted area of northern New South Wales.

It is an erect shrub with its end-branches sharply-pointed phylloclades, and yellow-orange flowers with red markings scattered along the branches.

[2][3] Jacksonia chappilliae was first formally described in 2007 by Carolyn F. Wilkins in Australian Systematic Botany from specimens collected by John Beaumont Williams west of Woodenbong in 1994.

[4] The specific epithet (chappilliae) honours Jennifer Anne Chappill, the principal research scientist in the revision of Jacksonia.

[2] This species of Jacksonia grows in heath and scrub on trachyte outcrops and is only known from the Woodenbong and Koreelah districts in far northern New South Wales.
