The Rhino (Aleksei Mikhailovich Sytsevich) is a comic book supervillain in the Marvel Comics universe, and an enemy of Spider-Man. Physically, he is one of Spider-Man's strongest foes with his favoured attack being ramming into a target with a sustained charge. He is also not very bright, and thus not too difficult for the wall-crawler to best.

The source of the Rhino's powers is his costume which resembles a rhinoceros, which was once permanently attached. Eventually, the abilities of the costume merged with the body of the wearer. He has been physically improved over the years by several other villains. This includes treatment with gamma rays to give him a similar physical constitution to the Hulk.
