Our Girl is a British television military drama series written and created by Tony Grounds. Its feature-length television pilot first broadcast on BBC One on 24 March 2013 and initially starred Lacey Turner as Molly Dawes, a young working-class woman, who joins the British Army after deciding her life is going down the drain. Following the feature-length pilot episode, a continuation show was commissioned, with Turner reprising her role for the first series, which commenced broadcast on 21 September 2014.

Turner left her show after the first series, so when the show was greenlit for a second series, Michelle Keegan was cast as a new character, Georgie Lane, to serve as the series' protagonist. The second series began airing on 7 September 2016. A split third series, comprising 12 episodes, was commissioned in 2017. The first four episodes, known as the Nepal Tour, began broadcasting on 10 October 2017. The remaining eight episodes aired consecutively from 5 June 2018. In January 2019, it was confirmed by the BBC that Keegan would return for a fourth series; she also announced that it would be her last series. It began broadcasting on 24 March 2020. Following Keegan's departure, it was confirmed in August 2020 that the fourth series of Our Girl would be its last.

Much of the show's filming and preparation took place in South Africa, with the location being used to depict Afghanistan in the show's first and fourth series, Kenya in its second, and being used to prepare actors for the conditions of filming while wearing heavy military attire. The third series was filmed in Nepal, where the series took place, for its first part, and Malaysia was used to portray Belize in its second.

Across its run, Our Girl received mixed reception, with reviews leaning more positively for the show's pilot and first two series, and more negatively for its third and fourth. While its production, performances, and action sequences were generally praised, critics agreed that the show glamourised military life and suffered a confused tone as the series progressed.
