Abraham Klein is an Israeli former international football referee. He refereed international matches between 1965 and 1982, including the 1968 and 1976 Olympics and important matches at the Mexico 1970, Argentina 1978 and Spain 1982 World Cup Finals. He was also a linesman (now assistant referee) for the 1982 World Cup Final in Spain.

Klein was also given the Brazil v Italy fixture in the 1982 World Cup, the game in which Paolo Rossi scored a hat-trick. He ran the line in the final to the Brazilian referee Arnaldo Coelho and was, reputedly, offered the chance to officiate in the event of that final being replayed.
