Nan Zhang is a Chinese American actress and model. She co-starred as Kati Farkas in The CW teen drama, Gossip Girl, until April 2008.

Born in Bengbu in the province of Anhui, China, Zhang and her family moved to the United States when she was six years old and settled in New Orleans, Louisiana. She is an only child. After being selected in Chanel/Seventeen Magazine's New Model of the Year contest at the age of 16, Zhang decided to pursue a possible career in modeling.

Graduating from Northshore High School in Slidell, Louisiana, she attended Tulane University but dropped out. She then transferred to Johns Hopkins University but again dropped out.

It is rumored that Zhang enrolled at Brown University during the writer's strike and didn't tell anyone, so she didn't appear in the show's return the month after. As a result, Nicole Fiscellaled Blair’s minion march alone.

Her acting debut came about when Zhang was discovered by a casting director while she was at a nail salon in New York which landed her a bit part in The Shanghai Hotel and followed with an uncredited bit part in West 32nd. Zhang's short lived break into showbiz came in March 2007 when she was cast in the supporting role of Kati Farkas in the television adaptation of the popular young adult novels, Gossip Girl.

Zhang has attempted to take up sports such as snowboarding and archery. She had previously wanted to be actively involved with neuroscience research but has stopped since quitting her studies.
