Robert Lewis Samuelson (born July 30, 1966) is an American former volleyball player. Samuelson won a bronze medal with the United States national team in the 1992 Summer Olympics in Barcelona.
At the Barcelona Olympics, Samuelson was the central character in the controversial preliminary round match against Japan in which the United States won until the result was overturned on appeal. A jury set up by the International Volleyball Federation ruled that by Samuelson having received his second yellow card, a red card and an automatic point to Japan should have been given, thus giving Japan the point they needed to win the match. The entire United States men's team then shaved their heads in solidarity with Samuelson.
