Jeffrey Alan Combs (born September 9, 1954) is an American actor. He is best known for starring as Herbert West in the H.P. Lovecraft adaptation Re-Animator (1985) and portraying a number of characters in the Star Trek universe, most notably Brunt and the various Weyouns on Star Trek: Deep Space Nine (1994–1999), and Shran on Star Trek: Enterprise (2001–2005).

Combs has been a prominent figure within the horror genre through most of his career, acting in eight films directed by Re-Animator director Stuart Gordon such as From Beyond (1986), The Pit and the Pendulum (1991), and Castle Freak (1995). Other horror film appearances include Necronomicon (1993), Peter Jackson's The Frighteners (1996), I Still Know What You Did Last Summer (1998), House on Haunted Hill (1999), and Would You Rather (2012). As a voice actor, Combs is best known as the voice of Question on Justice League Unlimited (2004–2006) and Ratchet on Transformers: Prime (2010–2013).

Combs was born in Oxnard, California, the fifth of nine children born to Jean Owens (formerly Sullins; 1921–1986) and Eugene "Gene" Combs (1922–1999), and raised in Lompoc. Both of his parents were from the Ozarks region of Arkansas. A graduate of Lompoc High School, as a senior, Combs played the lead role of Captain Fisby in a stage production of The Teahouse of the August Moon. Combs then attended Santa Maria's Pacific Conservatory of the Performing Arts, and later developed his acting skills in the Professional Actor's Training Program at the University of Washington from which he graduated in the late 1970s.

In 1980, after several years performing in playhouses on the West Coast, Combs moved to Los Angeles. He landed his first role in the film Honky Tonk Freeway (1981), playing an unnamed drive-in teller. His first horror film role came two years later in Frightmare (1983).^{[self-published source?]}

Combs's best-known horror role is Herbert West, the main character in the film Re-Animator (1985), and its two sequels. He portrayed author H. P. Lovecraft (creator of the Herbert West character) in the film Necronomicon: Book of the Dead (1993) and has starred in eight adaptations of Lovecraft's works. Other film credits include The Attic Expeditions (2001), FeardotCom (2002), House on Haunted Hill (1999), I Still Know What You Did Last Summer (1998) and The Frighteners (1996).

Combs has had roles in many science fiction television series. He starred as the telepath Harriman Gray in first-season episode "Eyes" (1994) of Babylon 5. In 2001, he played the sinister Dr. Ek in The Attic Expeditions. In August 2005, he appeared for the first time on the science fiction series The 4400 as Dr. Kevin Burkhoff which became a recurring role by 2006. In early 2007, he played a highly fictionalized Edgar Allan Poe in "The Black Cat" episode of Masters of Horror. In the 2012 miniseries Dorothy and the Witches of Oz (sometimes called The Witches of Oz), he had a small role as a fictionalized version of L. Frank Baum.

Combs has also worked as a voiceover artist. His voiceover roles include the Scarecrow in The New Batman Adventures, the Question in Justice League Unlimited, Ratchet in Transformers: Prime, the Leader in The Avengers: Earth's Mightiest Heroes, the Rat King in Teenage Mutant Ninja Turtles, and Brainiac in Injustice 2. He also narrated the 25th anniversary of Re-Animator at the 2010 FanTasia.

In July 2009, Combs returned to his stage roots and reprised his role as Edgar Allan Poe in a one-man theatrical show, Nevermore...an Evening with Edgar Allan Poe, at The Steve Allen Theater in Hollywood, California. Although it was supposed to run for only a month, it enjoyed much success and sold-out crowds, and was extended four times, until closing in Los Angeles on December 19, 2009. The show had its East Coast debut on January 23 and 24, 2010 at Westminster Hall in Baltimore, Maryland, Poe's final resting place. A tour of the Saturn Award-nominated Nevermore was subsequently planned.
