Spinaeschna tripunctata is a species of dragonfly in the family Aeshnidae, known as the southern cascade darner. It is a medium to large, dark brown dragonfly with greenish-yellow markings. It is endemic to eastern Australia, occurring in New South Wales and Victoria, where it inhabits streams and rivers.
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.
The species name tripunctata is derived from the Latin tres ("three"), punctum ("point" or "spot"), and the suffix -atus ("marked with"), referring to three well-defined spots on the second segment of the abdomen.
