Fat White Family are an English rock band, formed in 2011 in Peckham, South London.

The band, fronted by Southampton-born and Castlegar/Ayr/Cookstown-raised Lias Kaci Saoudi, formed in 2011. Lead guitarist Saul Adamczewski was previously the frontman of indie pop band the Metros, which also featured Fat White Family's bass player, Joe Pancucci. Nathan Saoudi previously played guitar with his older brother Lias in their former group, The Saoudis before becoming the keys player of Fat White Family. Adam Harmer (guitarist) had been a solo artist before joining the original six-piece lineup which also featured Dan Lyons on drums. The band would rehearse at the Queen's Head, Stockwell.

They released their debut album, Champagne Holocaust, in 2013, on UK label Trashmouth Records. It was released in 2014 in the U.S. on Fat Possum Records. The band released Fat Whites/Taman Shud, a split EP with Taman Shud, on 11 December 2013 on Trashmouth.

On 10 March 2014, Fat White Family issued their first single, "Touch the Leather", on Hate Hate Hate Records.

In early 2014, the band launched a PledgeMusic campaign to fund their show at the South by Southwest festival, with a subsequent US tour. Pledgers were given the self-released EP Crippled B-Sides and Inconsequential Rarities. Next was the single "I Am Mark E Smith" (referencing singer Mark E. Smith of the Fall), released on 15 December 2014.

Their second album, Songs for Our Mothers, was released in 2016 by the Without Consent label. Lias Saoudi described the album as an attempt to "really to get at the shittiness lurking in the core of my own soul, and in everybody else's". It was promoted with a single for "Whitest Boy on the Beach", which was later chosen for the closing credits of the 2017 film T2 Trainspotting.
