Goodenia byrnesii is a species of flowering plant in the family Goodeniaceae and is endemic to northern Australia.

Goodenia byrnesii is a prostrate to low-lying herb with stems up to 30 cm (12 in) long.

Flowering occurs from January to June and the fruit is a more or less spherical capsule 4–5 mm (0.16–0.20 in) in diameter.

[2][3][4] Goodenia byrnesii was first formally described in 1990 by Roger Charles Carolin in the journal Telopea from specimens collected near Elliott by Norman Byrnes.

[4][5] This goodenia grows on black soil plains in the Kimberley region of Western Australia, the northern part of the Northern Territory and the Burke district of north-west Queensland.
