Alexander Leipold (born 2 June 1969 in Alzenau in Unterfranken) is a German former freestyle wrestler who won the German Championships eleven times, the European Championships three times, the World Championships in 1994, and won the tournament at the 2000 Summer Olympics but was later stripped of his gold medal.
Leipold won the German Junior Championships in freestyle wrestling in 1985, 1986, 1988 and 1989, and was runner-up in 1987. After being runner-up in the German Championships in 1988 and 1989, he won in 1991, 1992, 1994–1999, 2002, 2003 and 2005, and was runner-up in 2004 and third in 1993.
He was runner-up in the European Junior Championships in 1985 and finished fifth in 1987. He won the European Espoir Championships in 1988, and finished sixth in the European Championships the same year before winning them in 1991, 1995 and 1998. He was runner-up in 1997 and 2003, and third in 1994 and 1999.
He won the World Espoir Championships in 1984 the World Championships in 1994, and was runner-up in 1995, 1997 and 1999, and third in 1998.
At the 1988 Summer Olympics, he finished seventh, in 1992 thirteenth, and at the 1996 Olympics fifth.
At the 2000 Summer Olympics, he won the freestyle tournament, winning the final 4–0 against Brandon Slay. Leipold then tested positive for norandrosterone and norethiocholanolone, which are used to prove the presence of the steroid nandrolone, and the gold medal was awarded to Slay. Prince Alexandre de Merode, the chairman of the IOC medical commission, was quoted as saying that Leipold's sample showed 20 nanograms of nandrolone per milliliter of urine, whereas the limit was 2 nanograms per milliliter.
The German Wrestling Federation suspended Leipold for two years, but the suspension was lifted because the federation had taken more than the permitted seven days to announce their decision.
Leipold had a receipt for 50 milliliters of urine for the B sample, but the laboratory report stated that 85 milliliters had been tested. He appealed the decision of the IOC and his suspension from competition was reduced from two years to one year, and he was not required to pay the costs.
