Early life 
Hennessy was born in Edmonton, Alberta. Her father, John Hennessy, was a meat salesman and sales/marketing executive, a job that required considerable travel and resulted in frequent moves for the family. Her mother, Maxine, a secretary, left the family in 1982, leaving her daughter to be partially raised by her paternal grandmother, Eleanor, in Kitchener, Ontario. She has a younger brother, John Paul "J.P." Hennessy, Jr., and an identical twin sister, Jacqueline, who is a magazine writer and TV show host in Canada. Hennessy has Irish, French, Swedish and Italian ancestry on her father's side, and mostly Ukrainian, as well as Austrian, ancestry on her mother's. She graduated from Grand River Collegiate Institute in Kitchener, Ontario and used to busk in the Toronto Subway.
In 1993, she played Dr. Marie Lazarus in RoboCop 3.
In 1999, she played Lisa in Chutney Popcorn. In 2000, Hennessy wrote, produced, and co-directed with Elizabeth Holder an independent film called The Acting Class. Inspired by a true story, the mockumentary looks at the trials and tribulations of a dysfunctional acting class. The film co-starred her sister, and included cameos by a number of Hennessy's former Law & Order co-stars. She also starred in the film Nuremberg as Elsie Douglas.
In 2001, she portrayed Jackie Kennedy in the film Jackie, Ethel, Joan: The Women of Camelot. In 2003, she made a cameo appearance in the film Abby Singer. From 2001 to 2007, she appeared on the TV show Crossing Jordan as Jordan Cavanaugh. Most recently, she portrayed Tim Allen's wife in the 2007 film Wild Hogs. On June 9, 2007, she received a star on Canada's Walk of Fame.
Hennessy has recorded an album in Austin, Texas, Ghost in My Head, which was released in June 2009. She performed as a guest of the Indigo Girls on a November 2009 show of Mountain Stage and was the focus of a show for herself later that same month. She performed on the Village Stage of the 2010 edition of Lilith Fair.
Hennessy starred in the independent crime thriller, Small Town Murder Songs, in 2010. She also appeared as a veterinarian in the HBO series Luck, while serving as an endorser of Zaxby's "Zalads" in a pair of television commercials during 2012.
Personal life 
Hennessy is multi-lingual, speaking English, Italian, French, Spanish and German. Hennessy plays the guitar and sings, and enjoys riding motorcycles with her husband, Paolo Mastropietro, to whom she has been married since 2000. They had a second marriage ceremony in January 2001, which took place at New York City Hall with Mayor Rudy Giuliani officiating. Their son, Marco, was born on September 17, 2003 and a second son, Gianni, was born on November 21, 2007.
Fan honors 
The Minneapolis-based band Mollycuddle wrote the song "The Ballad of Jill Hennessy" in honor of the actress. Hennessy was reportedly very pleased, and offered to perform with the band on rhythm guitar.
Hennessy represented Canada in the inaugural "Super-Hair World Cup" at the celebrity hair website Super-Hair.Net in 2002, and won the championship based on online voting.
