Elizabeth ("Beezie") Madden (born November 20, 1963 in Milwaukee, Wisconsin) is an American show jumping competitor and Olympic winner currently residing in Cazenovia, New York.

She is trained by her husband, John Madden, who also runs his business, John Madden Sales, from their farm in Cazenovia. Beezie frequently shows horses owned by John Madden Sales, but she also rides for other owners. Two of her most popular horses, Authentic and Judgement (who is now retired from the sport), are owned by Abigail Wexner and Iron Spring Farm, respectively.

At the 2004 Olympic Games in Athens, Madden won the gold medal as part of the United States team in Team jumping. At the 2008 Beijing Summer Olympics, Madden again earned gold in the Team Jumping competition. She also earned an Individual Brinze medal. In 2008 Beezie also placed first in the Animal Planet Sport Horse cup aboard Judgement.

Beezie has been asked, if she could start her life over again what would she do, and she admitted she would do the same thing. She was already riding at the age of three. Her first horse was called Flicka. In 2004 Madden was the first woman ever to pass the $1 million mark in showjumping earnings, a record she still holds.
