Petalura pulcherrima is a species of Australian dragonfly in the family Petaluridae,[3] commonly known as a beautiful petaltail.

[4] It is a very large and slender dragonfly, mostly black or dark brown with yellow markings and its eyes widely separated on top of its head.

[4] Petalura pulcherrima is endemic to coastal rainforests and monsoon-forest streams of Cape York in Queensland, Australia.

[5] Like other species of the genus Petalura, its larvae live in burrows beside rainforest streams, with an opening above water level.

The IUCN Red List considers it to be a vulnerable species, with fragmentation of its habitat by human interference a major factor.
