Leptospermum rupestre was first formally described in 1840 by botanist Joseph Dalton Hooker and the description was published in Icones Plantarum. Robert Brown observed it growing on rocky outcrops on Mount Wellington and nearby mountains. The word rupestre is derived from the Latin word rupestris, meaning rocky, referring to the habitat where it was found. Distribution and habitat
