1 January 1981
After graduating Armstrong appeared in Quartermaine's Terms at the Royal Theatre in Northampton as Derek Meadle. And in March 2004 he played Henry in The Skin of Our Teeth at the Young Vic theatre in the London Borough of Lambeth. In 2004 he appeared in six episodes of the fourth series of the British television comedy-drama, Teachers on Channel 4, as Anthony Millington. In January 2005 he appeared as Richard in Rutherford & Son at the Royal Exchange in Manchester. Later in 2005 he appeared again on Channel 4 in the crime drama series The Ghost Squad as Pete Maitland. In December 2006 he starred in the two-part crime drama Losing Gemma on ITV.
His first major television role came in October 2006 when he played Robin of Locksley, in the BBC's 2006 series based on Robin Hood. During filming of the second series, (which aired in 2007) Armstrong broke a metatarsal bone in his foot during a staged fight scene. Armstrong was a guest panelist on the BBC comedy panel game show Never Mind the Buzzcocks on 28 February 2007.
In August 2008, the BBC confirmed that Armstrong would be leaving Robin Hood at the end of the third season, which aired on 27 June 2009, with him saying that he was "looking for new challenges" and the BBC saying "he'll be desperately missed". The character of Robin was accordingly killed in the final episode, and the show was subsequently not renewed for a fourth series. In 2008 he appeared in the horror film Book of Blood which is based on a short story by Clive Barker.
He appeared in Episode 3 of the third series of BBC serial The Street broadcast on 27 July 2009, playing the role of TA soldier Private Nick Calshaw who returns from Afghanistan with a facial disfigurement and a prosthetic hand after being injured by a suicide bomber whom he was unable to shoot. In January 2009 Jonas Armstrong read CBeebies Bedtime stories on The Bedtime Hour.
