Rusingaceros or Dicerorhinus leakeyi is an extinct genus of rhinocerotid known from the Miocene of Rusinga Island, Kenya.

Both specimen were collected in the early Miocene site (Burdigalian stage) of Rusinga located in Lake Victoria in Kenya, from the Kulu Formation, dating to about 17.5 million years ago.

Additional specimens described by Hooijer in 1966 from the Songhor and Napak localities, as well as more recently reported occurrences, are highly fragmentary and based mostly on isolated teeth.

Rusingaceros represents the earliest rhino "of modern type, i.e., with a strong nasal and smaller frontal horn".

This suggests that Rusingaceros belongs to subtribe Rhinocerotina, within the tribe Rhinocerotini.
