Brandon Mroz is an American former competitive figure skater. He is the 2009 U.S. silver medalist and the 2006 & 2007 Junior Grand Prix Final silver medalist. He is the first skater to have completed a quadruple Lutz in a sanctioned competition.

A quadruple jump or quad is a figure skating jump with at least four revolutions. All quadruple jumps have four revolutions, except for the quadruple Axel, which has four and a half revolutions. The quadruple toe loop and quadruple Salchow are the two most commonly performed quads. Quadruple jumps have become increasingly common among World and Olympic level men's single skaters, to the point that not performing a quad in a program has come to be seen as a severe handicap. This phenomenon is often referred to as the "quad revolution". Since 2018, quadruple jumps have also become an increasingly common feature of women's skating, although they are not allowed under the International Skating Union ("ISU") rules in the ladies' short program. The first person to land a ratified quadruple jump in competition was Canadian Kurt Browning in 1988. Japanese skater Miki Ando became the first female to do so, in 2002.
