Stephen John Coogan was born on 14 October 1965 in Middleton, Greater Manchester, the fourth of six children in a large Irish Catholic family. His father Tony was an IBM engineer and his mother Kathleen fostered dozens of children during his upbringing β a chaotic, crowded household that Coogan has repeatedly credited as the making of him as a performer, honing impressions and voices to be heard above the din.
He trained at the Manchester Polytechnic School of Theatre, and his first professional break came in voice work on ITV's satirical puppet show Spitting Image, where he became one of the principal voice artists across the late 1980s and early 1990s, providing impressions of everyone from Neil Kinnock to Ronnie Corbett. Live club appearances, a Perrier Award win in 1992 and a series of Radio 4 collaborations with writer Armando Iannucci and comic Patrick Marber followed, out of which emerged the character that would define his career.
Alan Partridge β hapless sports reporter turned chat-show host turned Norwich local radio DJ β first appeared on the Radio 4 spoof news show On the Hour in 1991, graduated to his own radio series Knowing Me, Knowing You in 1992, then to BBC Two in 1994. The follow-up sitcom I'm Alan Partridge (1997 and 2002) is regularly cited among the greatest British sitcoms ever made, and the character has since sustained a webseries (Mid Morning Matters, 2010β12), a feature film (Alpha Papa, 2013), a spoof memoir (I, Partridge: We Need to Talk About Alan, 2011), the BBC One magazine-show parody This Time with Alan Partridge (2019β2021), and the mockumentary special How Are You? It's Alan (Partridge) (BBC One, 2025).
Around Partridge, Coogan has built one of the more varied careers in British comedy: the sketch vehicle Coogan's Run (1995), the surreal horror anthology Dr. Terrible's House of Horrible (2001), the Butlin's-Redcoat-turned-tour-manager sitcom Saxondale (2006β07), and the semi-fictionalised travelogue The Trip (2010β20) opposite Rob Brydon. In parallel he co-founded the production company Baby Cow with Henry Normal in 1999, whose credits include Gavin & Stacey, The Mighty Boosh, Nighty Night and Camping. Since the 2010s he has increasingly worked as a straight film actor and screenwriter: Philomena (2013), which he co-wrote and produced, earned four Academy Award nominations including Best Picture and Best Adapted Screenplay, and Stan & Ollie (2018) saw him play Stan Laurel to John C. Reilly's Oliver Hardy.
