Peter Oliveira is a Brazilian mixed martial artist from Fortaleza, Brazil. He currently competes in the middleweight division of the Japanese promotion KUMITE.
Brazilian-born Oliveira was the winner of the light heavyweight tournament at the unsanctioned, HCL-sponsored KUMITE: Hurricane show. He had done this without winning a single HCL fight going into the show, and surprised many by scoring a decision win in the final against Father Chad DiGreco.
Oliveira was released from his HCL contract on Friday, November 29, 2013, after six fights and a record of 2-4.
