Goodenia armstrongiana is a species of flowering plant in the family Goodeniaceae and is native to northern Australia and New Guinea.

It is an erect to low-lying herb with egg-shaped to narrow elliptic leaves, sometimes with small teeth on the edges, racemes of white or yellow flowers with leaf-like bracts at the base, and oval fruit.

Flowering mainly occurs from January to July and the fruit is an oval capsule 4–6 mm (0.16–0.24 in) long.

[4][5] The specific epithet (armstrongiana) honours John Armstrong who collected the type material.

[6] This goodenia grows in woodland and savanna from Arnhem Land and the Victoria River district in the Northern Territory to north Queensland and New Guinea.
