Floridaceras is an extinct genus of rhinocerotid of the Miocene epoch (early Hemingfordian), endemic to North America, living from around ~20.6–16.3 Ma, existing for approximately 4.3 million years.

It was assigned to Rhinocerotidae by Wood (1964) and Carroll (1988); and to Aceratheriinae by Prothero (1998).

[2] Floridaceras was of unusually large size for a rhinoceros of the Hemingfordian.

It would have been roughly comparable to a black rhinoceros[3] in size, much larger than contemporaries such as the Menoceras.

Like many primitive Aceratheriines, it has no horn, relatively long limbs and brachydont dentition (indicating it was a browser).
