Bimbisula ("dawn booby") is an extinct genus of sulid bird known from fossils discovered in Pliocene rocks of South Carolina, United States.

Bimbisula melanodactylos is based on Charleston Museum PV2818, a partial skeleton including fragments of the skull, shoulder girdle, left upper arm, right hand, and fused hip vertebrae, and much of the right leg.

It was collected in 1980 by James Malcolm from a locality along the Seaboard Coast Line Railroad in Charleston County in the vicinity of the Dorchester Road overpass.

A second specimen assigned to the species, Science Museum of Minnesota P90.38.8, consists of a cranium discovered in October 1990 by Bruce Erickson near the Wando Terminal.

Bimbisula was a large sulid, comparable in size to smaller species of gannets, and its skeleton shows a combination of booby-like and gannet-like characteristics.
