The 2007 NBA betting scandal was a scandal involving the National Basketball Association (NBA) and accusations that an NBA referee used his knowledge of relationships between referees, coaches, players and owners to bet on professional basketball games. In July 2007, reports of an investigation by the Federal Bureau of Investigation (FBI) were made public, which alleged that during the 2005–06 and 2006–07 NBA seasons, referee Tim Donaghy bet on games in which he officiated.
