Cash Run (born 1997) is an American Thoroughbred racing filly.
In 1999, she won the Breeders' Cup Juvenile Fillies and finished second in Eclipse Award balloting to Chilukki.
She won the Bonnie Miss Stakes and Davona Dale Stakes at Gulfstream Park in the first part of her 3-year-old season, but her form dropped off sharply after that.
She ran third in two stakes in her next eight races, and was retired with five wins from 17 starts.
