Dominic Monaghan

Monaghan was born in West Berlin, West Germany, to British parents: Maureen, a nurse, and Austin Monaghan, who was of Irish descent, a science teacher. Monaghan's family lived in Berlin, Düsseldorf, Stuttgart and Münster, moving about every four years. When he was about 11 years old, his family moved to Heaton Moor in Stockport, England. In Stockport, he attended St Anne's Roman Catholic High School (where his uncle taught and later became head teacher) and Aquinas College, where he studied English literature, drama and geography. Although Monaghan held many occupations when he was younger, he long wanted to be an actor. After his second year at St Anne's, Monaghan became a regular in school plays such as Oliver Twist, A Christmas Carol and Bugsy Malone before joining the Manchester Youth Theatre. There, he was scouted for Hetty Wainthropp Investigates, in which he starred alongside Patricia Routledge and Derek Benfield as Hetty's under-aged sidekick, Geoffrey Shawcross, for four series. Monaghan has since credited Routledge as "an amazing teacher" who taught him some "very valuable lessons" that have influenced his acting career. He made his feature-film debut as Russian sailor Sasha in the TV film Hostile Waters.

Monaghan later starred in The Lord of the Rings film trilogy as Meriadoc Brandybuck, for which he achieved international acclaim and success. Monaghan narrated Ringers: Lord of the Fans, a documentary about The Lord of the Rings fandom. He also provided the narration for The Discovery Channel's documentary Devil's Bible in 2008. He also appeared in Soldiers of Fortune alongside Sean Bean and Christian Slater.

He was a regular cast member on the ABC series Lost from 2004 to 2007, playing English former rockstar and drug addict Charlie Pace. Monaghan originally auditioned for the role of Sawyer. The role of Charlie was then changed from an old, washed up rocker from the 1980s, to a young one-hit wonder to accommodate Monaghan's age. Monaghan returned to the series as a special guest star after departing from the main cast.

In 2009, Monaghan starred as Chris Bradley / Bolt in X-Men Origins: Wolverine. On 15 July 2009, it was confirmed that he would join the cast of ABC Studios' science-fiction television series FlashForward as the character Simon. The series premiered on 24 September 2009. It was cancelled after its first season.

On 18 March 2010, Monaghan was spotted at the Universal Sheraton filming a short titled Gloria. It was part of a programme titled REESES Puff's Extraordinary Cinema (where the teenagers replace the pros). He played the part of Caleb Reese.

In 2010, Monaghan and US actress Megan Fox made an appearance as a couple in an abusive relationship in the music video for Rihanna and Eminem's song "Love the Way You Lie". Scenes include the celebrities on top of a liquor store. Fox and Monaghan also filmed inside the store and "at a seedy dive bar next door" to the store.

In November 2012, a new show on Channel 5 titled Wild Things with Dominic Monaghan started airing in the United Kingdom. The documentary shows Monaghan travelling to different locations such as Venezuela and Ecuador to film and interact with the exotic and often dangerous local wildlife.

During the summer of 2013, Monaghan appeared in various live-action teasers for 2K Marin's science-fiction video game The Bureau: XCOM Declassified.

Monaghan is a fan of The Gaffer Tapes: Fantasy Football Podcast and has appeared as a guest in both April-November 2016 and May 2018, as well as submitting several audio questions which are played on the podcast. While appearing as a guest, Monaghan said "It's the best fantasy football podcast out there".

Monaghan is a contributing writer for the music and culture magazine Paste, primarily writing articles about Premier League football.

Monaghan is the voice of Sightseeing Manchester's bus tour, recorded in March 2016.

Since August 2018, he has been starring as a serial killer in Channel 9 Australia's murder-mystery/drama TV series Bite Club, which is filmed in and around Sydney.

He was named as part of the cast for the last film in the sequel trilogy which is Star Wars: The Rise of Skywalker, reuniting with J.J. Abrams, the co-creator of Lost. He appeared as Beaumont.

In May 2020, Monaghan joined together with fellow Lord of the Rings castmates, along with writer Philippa Boyens and director Peter Jackson, to appear on Josh Gad's YouTube series Reunited Apart, which reunites the cast of popular films through video-conferencing, and promotes donations to non-profit charities. Monaghan and castmate Billy Boyd started the podcast The Friendship Onion where they talk about their time filming The Lord of the Rings.

He made his stage debut in 2024 with Lord of the Rings castmate Boyd in the Canadian production of Tom Stoppard's Rosencrantz and Guildenstern Are Dead.
