Yuri van Gelder (born 20 April 1983) is a Dutch gymnast, whose best discipline is the rings. His nickname is "Lord of the Rings".
Born in Waalwijk, Netherlands, Van Gelder took the gold in the men's rings at the 2005 European Championships held in Debrecen, Hungary. He became world champion in the same discipline at the 2005 World Artistic Gymnastics Championships in Melbourne, Australia. He won bronze at the 2006 World Artistic Gymnastics Championships in Aarhus, Denmark. At the 2007 World Artistic Gymnastics Championships in Stuttgart, Germany, he won a silver medal.
On July 13, 2009, he revealed that he used cocaine three days before the Dutch championships in Rotterdam. Van Gelder said he very much regretted his "lapse" and called himself "incredibly stupid". He has since had to return his national championship gold medal, and was suspended by the Dutch Gymnastics Union. IOC regulations implied that because of the suspension he would not be admitted to the Olympic Games in 2012. He was also fired from his job with the Dutch military, as they have a 'zero tolerance' drugs policy.
