Petalura gigantea, the giant dragonfly or south-eastern petaltail, is a species of dragonfly in the family Petaluridae from southeastern Australia. Males have body length of 6–7.5 cm (2.4–3.0 in) and a wingspan up to 11 cm (4.3 in), while females have body length of 8–9 cm (3.1–3.5 in) and a wingspan up to 12.5 cm (4.9 in). This makes it a very large species of dragonfly, although it is exceeded by a few other species, including the closely related northeast Australian giant petaltail.
