Father Ted is a sitcom created by Irish writers Graham Linehan and Arthur Mathews and produced by British production company Hat Trick Productions for British television channel Channel 4. It aired over three series from 21 April 1995 until 1 May 1998, including a Christmas special, for a total of 25 episodes. It aired on Nine Network (series 1) and ABC Television (series 2 and 3) in Australia, and on TV2 in New Zealand.

Set on the fictional Craggy Island, a remote location off Ireland's west coast, Father Ted stars Dermot Morgan as Father Ted Crilly, alongside fellow priests Father Dougal McGuire (Ardal O'Hanlon) and Father Jack Hackett (Frank Kelly). Dishonourably exiled on the island by Bishop Leonard Brennan (Jim Norton) for various reasons, the priests live together in the parochial house with their housekeeper Mrs Doyle (Pauline McLynn). The show subverts parodies of low-brow humour as it portrays nuanced themes of loneliness, agnosticism, existentialism and purgatory experienced by its title character; this deeper meaning of the show has been much acclaimed.

Father Ted won several British Academy Television Awards—including twice for Best Comedy Series, and remains a popular sitcom in Ireland and the UK. In a 2001 Channel 4 poll, Dougal was ranked fifth on their list of the 100 Greatest TV Characters. In 2019, Father Ted was named the second-greatest British sitcom (after Fawlty Towers) by a panel of comedy experts for Radio Times.

The show follows the misadventures of three Irish Roman Catholic priests who live in a parish on the fictional Craggy Island, located off the west coast of Ireland. Father Ted Crilly, Father Dougal McGuire and Father Jack Hackett live chaotically together in Craggy Island's parochial house, along with their housekeeper Mrs Doyle, who always wants to serve them tea.

The three priests answer to Bishop Len Brennan, who has banished them to Craggy Island as punishment for different incidents in their past: Ted for alleged financial impropriety (apparently involving some money "resting" in his account and a child being deprived of a visit to Lourdes so that Ted could go to Las Vegas), Dougal for an event only referred to as the "Blackrock Incident" (resulting in "many nuns' lives [being] irreparably damaged"), and Jack for his alcoholism and womanising, particularly for an unspecified incident at a wedding in Athlone.

The show revolves around the priests' lives on Craggy Island, sometimes dealing with matters of the church but more often dealing with Father Ted's schemes to either resolve a situation with the parish or other Craggy Island residents, or to win games of one-upmanship against his enemy, Father Dick Byrne of the nearby Rugged Island parish.

Graham spent a lot of time listening to the Pixies and watching Taxi Driver. When I knew him first, it was like he'd never been outside the house, except to go to see Star Wars films, so his influences were never that Irish, whereas I grew up in the country... I remember Frank Kelly and Hall's Pictorial Weekly. He did a show called The Glen Abbey Show, which was very funny. So I was always aware of the strangeness and madness of Irish things.

Linehan and Mathews first met while working at Hot Press. In the late 1980s, Mathews, Paul Woodfull and Kieran Woodfull formed The Joshua Trio, a U2 tribute band. The trio began writing comedy sketches to accompany their act. Mathews created the Father Ted character for his short-lived stand-up routine. Before The Joshua Trio played at gigs, Mathews would occasionally come on-stage as Father Ted and tell jokes involving his great friend, Father Dougal McGuire.
