Kirsty Hume (born September 4, 1976) is a Scottish model who came to prominence in the fashion world in the 1990s. A columnist likened her appearance to a Botticelli angel.

She is married to rocker and actor Donovan Leitch, Jr.. After getting married in Scotland in 1997, they drove all around Bali in a jeep. The couple have a daughter named Violet.

In 1996 Hume was the feature model for Chanel ads. She has modelled for Victoria's Secret. For the March 1996 Gucci presentation of fall and winter fashion collections in Milan, Italy, Hume wore a fabulous dress made of white jersey (clothing) with a plunging neckline.

Following a 1997 Paris, France showing of Karl Lagerfeld designs for Chanel, Hume was queried by a Russian TV reporter. He asked her what was the most exciting part of her job. She answered, Um, the money. She appeared in a bias-cut chiffon gown designed by Donatella Versace at the January 1998 Milan fashion show.

Hume patronized the 26th Street flea market in Manhattan when shopping for Momo Falana, a line of hand-dyed dresses made from vintage lingerie. Parker Posey and Donna Karan were also customers of the business, which sells to patrons by appointment only.

Hume attended a Halloween party at Lot 61 in Chelsea, Manhattan, with Leitch and Oliver Stone, in 1998. The Japanese-themed event included an appearance by Leonardo DiCaprio and friends dressed as members of Kiss. Hume arrived in fangs. The night before Halloween in 1999 Leitch and Hume hosted a party at the same venue. Hume was draped in vines and the couple were scantilly dressed as Adam and Eve.

Hume and Leitch eschewed city life and relocated to Woodstock, New York. Hume began to study painting and paganism after their move. She is fond of wearing flip flops and Birkenstocks.
