The rock parrot (Neophema petrophila) is a species of grass parrot native to Australia. Described by John Gould in 1841, it is a small parrot 22 to 24 cm (8+3⁄4 to 9+1⁄2 in) long and weighing 50–60 g (1+3⁄4–2 oz) with predominantly olive-brown upperparts and more yellowish underparts. Its head is olive with light blue forecheeks and lores, and a dark blue frontal band line across the crown with lighter blue above and below. The sexes are similar in appearance, although the female tends to have a duller frontal band and less blue on the face. Two subspecies are recognised.
