The 2002 Olympic Winter Games bid scandal was a scandal involving allegations of bribery used to win the rights to host the 2002 Winter Olympics in Salt Lake City, Utah, United States. Prior to its successful bid in 1995, the city had attempted four times to secure the games; failing each time. In 1998 members of the International Olympic Committee (IOC) were accused of taking bribes from the Salt Lake Organizing Committee (SLOC) during the bidding process. The allegations resulted in the expulsion of several IOC members, and the adoption of new IOC rules. Legal charges were brought against the leaders of Salt Lake's bid committee by the United States Department of Justice, of which all parties were later acquitted. Investigations were also launched into prior bidding process by other cities, finding that members of the IOC received gifts during the bidding process for both the 1998 Winter Olympics and 2000 Summer Olympics.

The Scandal broke on 10 December 1998, when Swiss IOC member Marc Hodler, head of the coordination committee overseeing the organization of the 2002 games, announced that several members of the IOC had taken bribes. Soon four independent investigations were underway: by the IOC, the USOC, the SLOC, and the United States Department of Justice.

As a result of the investigation, ten members of the IOC were expelled and another ten were sanctioned. This was the first expulsion or sanction for corruption in the more than a century the IOC had existed. Although nothing strictly illegal had been done, it was felt that the acceptance of the gifts was morally dubious. Stricter rules were adopted for future bids and ceilings were put into place as to how much IOC members could accept from bid cities. Additionally new term and age limits were put into place for IOC membership, and fifteen former Olympic athletes were added to the committee.

In 2006, a report ordered by the Nagano region's governor said the Japanese city provided millions of dollars in an "illegitimate and excessive level of hospitality" to IOC members, including US$4.4 million spent on entertainment alone.
