The inland thornbill (Acanthiza apicalis) was originally described by English ornithologist John Gould in The Birds of Australia. Inland thornbills are within the order passerines. The inland thornbill belongs to the genus Acanthiza, which now has three more species than the eleven outlined by Gould in The Birds of Australia. The Noongar people of southwestern Western Australia call A. apicalis "Djoobi-Djoolbang". The inland thornbill is also known as the broad-tail thornbill and presently contains several subspecies that were once considered independent species. The word apicalis comes from the Latin for 'tipped'.
