Nora Kristina Greenwald (born September 7, 1977), better known by her ring name Molly Holly, is an inactive American professional wrestler. Greenwald is best known for her appearances with World Championship Wrestling (WCW) and World Wrestling Entertainment (WWE).

Greenwald began her professional wrestling career in WCW, where she also worked as a trainer. In WWE, Greenwald debuted as one of The Holly Cousins, an alliance of storyline cousins. She was later aligned with The Hurricane. In a Hair versus Title match at WrestleMania XX in March 2004, Greenwald had her head shaved as a result of losing a match against Victoria. Greenwald is also a two time Women's Champion and one of the few women to hold a male title in WWE, holding the Hardcore Championship once.

Greenwald was born to parents Rick and Bonnie Greenwald. She has two brothers, Luke who lives in Utah and Chancey who is a dental hygienist. Growing up, Greenwald had no plans to be a wrestler, but she claims to have wanted to be on American Gladiators for a while. She trained to be a powerlifter from age 14 to age 18, and at age 14, she broke the Minnesota state powerlifting record (75 pounds) for her age group by lifting 100 pounds. She also trained as a gymnast. Later, she began wrestling for fun, not because she "wanted to be on TV."
