Zieria is a genus of plants in the citrus family Rutaceae family. About sixty species have been formally described, all of of which are endemic in Australia except for one species which is found in New Caledonia. They occur in all Australian states except Western Australia but the genus is under review and a number of species are yet to be described or the description published. Zierias are similar to the better known Boronia genus but can be distinguished by the number of stamens in the flowers. The name Zieria honours the Polish botanist John Zier.
