Calytrix smeatoniana is a species of flowering plant in the myrtle family Myrtaceae and is endemic to Kangaroo Island in South Australia.

It is a shrub with hairy branchlets, linear to narrowly elliptic leaves and white to pale pink flowers with about 18 to 22 stamens in a single row.

The sepals are narrowly elliptic or reduced to an irregular rim at the base of the floral tube, 2–3 mm (0.079–0.118 in) long, and lack an awn.

[2][3] This species was first formally described in 1887 by Ferdinand von Mueller who gave it the name Lhotskya smeatoniana in The Australasian Journal of Pharmacy from specimens collected by Otto Tepper on Kangaroo Island.

[2][5] The specific epithet (smeatoniana) honours Thomas Smeaton, a member of the Royal Society of South Australia and who has "much promoted the natural sciences in the neighbouring colony".
