Holly Marie Combs (born December 3, 1973) is an American actress and television producer, best known for her role as Piper Halliwell on The WB television series Charmed (1998–2006). During the mid-1990s, Combs appeared as Kimberly Brock on the CBS television series Picket Fences (1992–1996), which earned her a Young Artist Award. She also starred in films such as Sweet Hearts Dance (1988), Born on the Fourth of July (1989), Dr. Giggles (1992), Sins of Silence (1996), Daughters (1997) and Love's Deadly Triangle: The Texas Cadet Murder (1997). Recently Combs starred in the ABC Family television series Pretty Little Liars (season 1–3) as Ella Montgomery. She left the show during season 4, but promised to back later.

Although she had a number of minor roles in the late 1980s, including a brief speaking part in Oliver Stone's Born on the Fourth of July, Combs' major acting debut arrived in the 1992 TV drama series Picket Fences. She auditioned for the role of Kimberly while she was in New York. The casting agent told her that she wasn't right for the part because she "didn't have a big enough heart." Combs retorted, "If you're looking for someone with a big heart, what the hell are you doing in New York?" She was later called back and offered the job. Picket Fences ran for four years, winning Combs critical acclaim and a Young Artist award.

In 1992, Combs made her appearance in Simple Men, Chain of Desire, and Dr. Giggles, in which she plays its protagonist, the 19-year-old daughter of Cliff De Young's character and girlfriend of Glenn Quinn's character, Jennifer Campbell.

In 1996, she starred alongside Alyson Hannigan and Tangi Miller in a pilot called Friends for Life. The pilot wasn't picked up.

In 1997, she played real-life convicted murderess Diane Zamora in the television movie Swearing Allegiance, a far cry from her other good-girl roles. Combs was with her friend Shannen Doherty when Doherty was given the pilot script for Charmed. Doherty took Combs along to the audition when Combs said she wanted to take part in the audition. Combs auditioned for the role of Prue Halliwell and Doherty for Piper Halliwell, but they ended up switching roles. Alyssa Milano and Combs both became producers for Charmed in the fourth season. For the first three seasons of Charmed (which debuted in 1998 and was a hit TV series, ending in May 2006), Combs played the second oldest of the three sisters. When the eldest, Doherty, left after the third season and Rose McGowan joined the cast for the fourth season, Combs played the eldest sister for the remaining five seasons of the show. All the while she was the youngest of all four actresses.

In 2008, Combs signed a contract with Lifetime Television to produce and star in a new TV series, Mistresses which was originally scheduled to air in January 2009, but was not picked up.

Combs made her television comeback in June 2010 on ABC Family's new show Pretty Little Liars. Combs plays Ella Montgomery, the mother of main character Aria Montgomery (played by Lucy Hale).

Combs attended Anaheim Comic Con with former Charmed co-stars Shannen Doherty (Prue) and Victor Webster (Coop) on April 17, 2010.
