Nancy Faust (born March 11, 1947) is an American former stadium organist for Major League Baseball's Chicago White Sox.

Faust grew up in the Chicago area, and began playing the organ at age 4 by learning from her mother, Jacquin, also a professional musician.

She was hired to succeed Bob Creed as the White Sox organist for the 1970 season by public relations director Stu Holcomb, who had seen her perform at a banquet.

Her original perch at Comiskey Park was an organ booth that was established in the center field bleachers in 1960 by Bill Veeck to encourage fan interaction.

In the 1970s, Faust – along with announcers Harry Caray and Jimmy Piersall, plus Andy the Clown – became great crowd favorites at Comiskey Park.

[1] Having become the team's "key player," Faust found herself appearing on ABC's Good Morning America and written up in Sports Illustrated as baseball's "MVO, or Most Valuable Organist", among other accolades.

Fans enjoyed being able to visit Faust during games and offer suggestions – first in her open-air position in Comiskey Park's upper deck, and later in a booth behind home plate at U.S. Cellular Field.

Aside from the Sox (1970–2010), Bulls (1976–1984) and Blackhawks (1984–1989), she was organist for the Sting pro soccer team (1975–1988) and DePaul University Blue Demons basketball (1977–1981).

[3] Ten thousand Nancy Faust bobblehead dolls were presented to fans by the White Sox before their game on September 18, 2010, at then-U.S. Cellular Field, with a ceremony held by the team in her honor.
