Spinaeschna watsoni is a species of dragonfly in the family Aeshnidae, known as the tropical cascade darner. It is a medium to large, dark brown dragonfly with greenish-yellow markings. It is endemic to north-eastern Australia, where it inhabits streams and rivers.
Etymology The genus name Spinaeschna is derived from the Latin spina ("thorn" or "spine"), combined with -aeschna, a suffix commonly used for dragonflies associated with the Aeshna group. The name likely refers to a large spine on the male appendages.
In 1982, Günther Theischinger named this species watsoni, an eponym honouring the entomologist Tony Watson (1935–1993), his friend and supporter.
