Maura Tierney

In 2019, Tierney originated the lead role of Elizabeth in the West Coast premiere of Jen Silverman's play Witch at the Geffen Playhouse, directed by Marti Lyons.

In 2018, Tierney co-starred with Steve Carell and Timothée Chalamet in the dark family drama film Beautiful Boy, based on the memoir of the same name by David Sheff. In 2019, Tierney appears in The Report as "an intense, driven, somewhat vengeful Counterterrorism expert determined to get behind any program that promises to get the intel that will stop another attack from happening."

In September 2012, Tierney began a recurring role on the CBS legal drama The Good Wife, playing Maddie Hayward. In 2013, Tierney joined the cast of Showtime's The Affair, playing Helen Solloway, for which she won the Golden Globe Award in 2016.

In February 2011, Tierney made her debut at the Gate Theatre in the Dublin premiere of Yasmina Reza's God of Carnage (translation by Christopher Hampton) alongside Ardal O'Hanlon. Also in 2011, Tierney appeared in one episode of The Office (S8E9: Mrs. California) as Robert California's wife.

Tierney returned to television, playing the recurring character Kelly McPhee on the FX series Rescue Me in 2009 and 2011 during its final season. She replaced Joely Richardson as the female lead of the 2010 ABC television series The Whole Truth after Richardson left to spend more time with her family. Tierney's role in the show, a legal drama produced by Jerry Bruckheimer, marked her return to television after recovering from breast surgery and cancer treatments. ABC canceled The Whole Truth after four episodes owing to low ratings.

On February 1, 2009, the recently ordained Tierney officiated at the wedding of her friend and former ER co-star Parminder Nagra to photographer James Stenson.

Tierney had surgery to remove a tumor from her breast in 2009. She had been cast in Parenthood but schedule conflicts with her cancer treatments led her to leave and she was replaced by Lauren Graham. Tierney finished treatment and returned to work in a stage play in 2010.

Tierney confirmed in April 2008 that she would be leaving ER shortly after the beginning of the show's fifteenth season. In October 2008, she made her final regular appearance on the series after nearly 10 seasons on the show. She returned to make a cameo appearance in one additional episode later in 2009 toward the end of the final season.

In 2004, Tierney won the second-season tournament of Bravo's Celebrity Poker Showdown against Lauren Graham, who had a guest role in the fourth season of NewsRadio. Tierney returned to the stage in May 2006 in an appearance opposite Eric McCormack in the Off Broadway premiere of Some Girl(s). She also appeared in the 2008 films Semi-Pro, Baby Mama, The Go-Getter and Finding Amanda. Tierney also played the role of Laurel in the Off Broadway play Three Changes with Dylan McDermott from September 16 to October 4, 2008.

Tierney's highest-profile film while being part of the ER cast was the 2002 film Insomnia, which was directed by Christopher Nolan. That same year, she also starred in Scotland, Pa. where she portrayed a Lady Macbeth-like character written specifically for her by Billy Morrissette, her husband at the time. She was praised by critics for her performance. She also collaborated with NewsRadio writer Joe Furey for a special "Working with Joe Furey" featurette for Furey's film Love and Support.

From 1999 to 2008, Tierney played Nurse Abigail "Abby" Lockhart on ER, a character that began as a guest appearance in November 1999 and then expanded in February 2000 to a full-time regular role as an ER nurse and later after completion of medical school, a doctor. She was reunited with her NewsRadio co-star Khandi Alexander, who at that time also had a recurring role on ER. Within a year, Tierney's work on ER earned her an Emmy Award nomination, a recognition she credits to a "juicy" story arc featuring Sally Field as Lockhart's mother Maggie Wyczenski, who has bipolar disorder.

Tierney appeared in numerous films, including Primal Fear (1996), Liar Liar (1997), Primary Colors (1998), Forces of Nature (1999), Insomnia (2002), Semi-Pro (2008), Baby Mama (2008), Beautiful Boy (2018), and The Report (2019).

Tierney had a number of small roles in film and television (including a role in 704 Hauser, a short-lived 1994 spin-off of All in the Family), but first received regular national exposure with her leading role in the sitcom NewsRadio from 1995 to 1999. While part of the NewsRadio cast, she also starred in several successful films of the late 1990s and early 2000s such as Primal Fear, Liar Liar, Primary Colors, Forces of Nature and Welcome to Mooseport.

Tierney married actor/director Billy Morrissette on February 1, 1993, two days before her 28th birthday after the two met on the set of an unaired television series. She filed for divorce in 2006 due to irreconcilable differences. They did not have any children.

After appearing in several plays, Tierney moved to Los Angeles, California in 1987 where her big break was a role in Disney's made-for-TV film Student Exchange. Tierney's first starring role in a film was in a low-budget independent film called Dead Women in Lingerie, which was shot in 24 days. Despite receiving a DVD release in 2005, the film has yet to also receive a theatrical release.
