Emanuel Fernando Sheffer Rego is a male former beach volleyball player from Brazil who competed in five consecutive Summer Olympics, starting in 1996. He won the gold medal in the men's beach team competition at the 2004 Summer Olympics in Athens, Greece, partnering with Ricardo Santos. He famously offered his medal to his compatriot Vanderlei de Lima – who won a bronze in the men's marathon after being attacked by Neil Horan – a year later, though it was politely declined.

Beach volleyball is a team sport played by two teams of two players each on a sand court divided by a net. Similar to indoor volleyball, the objective of the game is to send the ball over the net and to ground it on the opponent's side of the court. Each team also works in unison to prevent the opposing team from grounding the ball on their side of the court.
