Rafael "Rafinha" Betim Marti (born 23 November 1987) is a Brazilian footballer who played for Bovista Timor Leste of the East Timor club Liga Futebol Amadora.
Traded to New Radiant of the Maldivian Premier League from Portugal's SCU Torreense in 2015, Betim Marti was sacked alongside two other foreigners due to putting in what the club thought was a languorous performance in the 2015 POMIS Cup. Shortly after, the Brazilian forward joined T.C. Sports Club.
