The Commitments (1987) (originally to be called The Partitions) is a novel by Irish writer Roddy Doyle. The first episode in The Barrytown Trilogy, it is about a group of unemployed young people in the north side of Dublin, Ireland, who start a soul band.

Doyle wrote the novel while working as a teacher in Kilbarrack, Dublin. Although it is his publishing debut it was not the first novel he wrote, and he had written for the stage, his play Brownbread being produced by Passion Machine, a theatre company with a special interest in working-class Dublin stories, in 1987. It was directed by Paul Mercier.

Encouraged by positive feedback for the script of Brownbread in Dublin and following numerous rejections he self-published The Commitments, creating the King Farouk press (King Farouk is Dublin rhyming slang for a book, book being pronounced "buke" in Dublin) with Passion Machine producer John Sutton. Following a successful local run of 2,000 books which sold out in six months, the novel was picked up by William Heinemann to be published in the UK. An endorsement from Elvis Costello brought the book to wider attention.

Two friends — Derek Scully and "Outspan" Foster — get together to form a band, but soon realise that they don't know enough about the music business to get much further than their small neighbourhood in the Northside of Dublin. To solve this problem, they recruit a friend they'd had from school, Jimmy Rabbitte, to be their manager. He accepts graciously, but only if he can make fundamental changes to the group, the first being the sacking of the third, and mutually disliked, member — their synth player. After this, Rabbitte gets rid of their name, making them "The Commitments" (stating "All the good 60s bands started with a 'the'") and, most importantly, forming them from another synthpop group into the face of what he thinks will be the Dublin-Soul revolution ("Yes, Lads. You'll be playing Dublin Soul!").

He witnesses a young man singing drunkenly into a microphone at a friend's wedding and is struck by the fact he is singing "something approximating music". Jimmy places an ad in the local paper reading "Have you got soul? Then Dublin's hardest working band is looking for you". Eventually, he gets together a mismatched group with seemingly no musical talent, led by mysterious stranger Joey "The Lips" Fagan, who claims to have played trumpet with Joe Tex and the Four Tops. They quickly start learning how to play their instruments and perform a number of local gigs.

With music fanatic Jimmy Rabbite as their manager, the Commitments seek to fulfil their goal of bringing soul to Dublin. In the beginning, Jimmy includes all of the country Ireland, but later realises that the culchies have everything whereas the Dubliners are the working-class and have nothing. Bringing soul music to Ireland is then reduced merely to the city.

Tensions run high between the band members, not helped by the jealousy and animosity Joey receives from other male members due to the attention he receives from the female backing singers. The band slowly becomes more and more musically competent and draws bigger and more enthusiastic audiences. But the band falls apart after a gig when Joey is seen kissing Imelda and a fight ensues — all while Jimmy is negotiating to record the band's first single with an independent label.

Fagan soon goes to America after Imelda tells him she is pregnant (it turns out she was actually lying, only saying this for the attention). In the end, Jimmy, along with the band's other founding members and Mickah, form The Brassers, an Irish hybrid of punk and country. They plan on inviting James into the band after he's finished his medical degree, and they discuss getting the ladies involved as well.
