Irina Eduardovna Slutskaya (born February 9, 1979) is a Russian figure skater. She is a two-time World Champion (2002, 2005), two-time Olympic medalist (silver in 2002, bronze in 2006), seven-time European Champion (1996, 1997, 2000, 2001, 2003, 2005, 2006), a four-time Grand Prix Final Champion (2000–2002, 2005) and a four-time Russian National Champion (2000–2002, 2005). Slutskaya, known for her athletic ability, was the first female skater to land a triple lutz-triple loop combination. She is also known for her trademark double Biellmann spin with a foot change, which she also invented. She is generally considered to be the most successful ladies' singles skater in Russian history.
