Brendan Joseph Hansen (born August 15, 1981 in Havertown, Pennsylvania) is an American swimmer who specializes in the breaststroke. He is a four-time Olympic medalist and multiple record holder. He attended St. Denis School in Havertown, PA.
At the 2005 World Aquatics Championships, Hansen won gold in the same three events that he participated in at the 2004 Olympics.
Hansen's well-known for his unique style of breaststroke, which incorporates a kick that is much narrower than the other swimmers, including his biggest rival, Kosuke Kitajima from Japan, who took gold in both the 100 m and 200 m Breaststroke in 2004 Athens Olympic Games.
At the 2006 ConocoPhillips National Championships, Hansen lowered both his world records in the 100 meter and 200 meter breaststroke to 59.13 in the 100 m and 2:08.74 in the 200 m.
At the 2006 Pan Pacific Swimming Championships held in Victoria, Canada, Hansen again lowered his world record time in the 200 m breaststroke to 2:08.50. It is notable that he was a quarter of a second behind his best time at the 150 m mark, but he came back 0.6 second faster with a 33.38.
Hansen was the world record holder in the (long-course) 100 m breaststroke until Kitajima broke that record at the 2008 Olympics. The 200 m breaststroke record he set in 2006 was broken by Kitajima in June 2008.
He was also NCAA Champion in the 100 yard and 200 yard breaststroke events each year of his four year college career.
Hansen swam breaststroke at the 2008 Summer Olympics, his only individual event, finishing in fourth place but earned a gold medal for his part in the 4 x 100 Medley Relay. He lost the medal while on a flight home from a party in his hometown near Philadelphia to Austin. It was returned to him the following day.
