Bursatella hirsuta is a species of large sea slug or sea hare, a marine gastropod mollusk in the family Aplysiidae, the sea hares.

[2] This species occurs on the south coast of Australia and in Western Australia, where it was previously mistaken for Bursatella leachii.

[1] The adult has a distinctive humped back and all-over brown hairy projections, finer than those in B. leachii, but juveniles of the two species are easily confused.

Its range apparently overlaps with B. leachii in central Victoria.
