Naseem Hamed: $33 Million
Despite being physically smaller than most fighters on this list, Naseem Hamed's net worth is nothing to scoff at. Primarily competing in the bantamweight and featherweight divisions, Hamed enjoyed an almost unblemished career record except a 2001 loss to Marco Antonio Barrera. Hamed secured victory in 31 bouts by knockout, resulting in an impressive 84% knockout-to-win ratio. He is also known for his extravagant ring entrances, such as arriving on a flying carpet or reenacting Michael Jackson's "Thriller" video.
