Cyanicula caerulea was first formally described in 1810 by Robert Brown and the description was published in Prodromus [florae Novae Hollandiae]. In 2000, Stephen Hopper and Andrew Brown transferred the species to Cyanicula as C. caerulea. The specific epithet is a Latin word meaning "sky-blue".Distribution and habitat

In New South Wales and the Australian [Capital Territory|A.C.T.] it grows in woodland and shrub on rocky ridges, mostly in the eastern half of the state.
