Zieria inexpectata is a plant in the citrus family Rutaceae and endemic to south-eastern Queensland.

It was unexpectedly discovered by the authors during a field trip and its discovery led to a paper describing the zierias of Queensland, including sixteen new species.

Zieria inexpectata is a shrub which grows to a height of 50 cm (20 in) and has erect, wiry branches with scattered hairs.

[2] Zieria inexpectata was first formally described in 2007 by Marco Duretto and Paul Irwin Forster from a specimen collected near Gayndah and the description was published in Austrobaileya.

[2][3] This zieria grows in sandy soil in woodland in south-east Queensland, including the central Burnett district, and near Proston and Wondai.
