Comprising thirteen 45-minute episodes per series, Robin Hood was created by Dominic Minghella and Foz Allan, who serve as executive producers on the series, with Minghella the chief writer. Minghella was previously responsible for the successful ITV network comedy-drama series Doc Martin. Richard Burrell is the producer, and the other writers involved on the first series were Paul Cornell, Mark Wadlow, Debbie Oates, Kurti & Doyle and Joe Turner.

The first series had a reported budget of £8 million. The programme was specifically designed to run in the same Saturday evening family drama slot as the successful revival of Doctor Who, filling the slot in Doctor Who's absence between series. Shot in the high definition format, the programme also airs on the BBC's BBC HD service.

Robin Hood was announced as a possible commission by BBC One Controller Peter Fincham in July 2005, but not officially confirmed by Head of Drama Jane Tranter until 24 October that year. On 18 February 2006, the Daily Mirrornewspaper announced that actor Jonas Armstrong had been cast in the lead role in the series. This was confirmed by the BBC in a press release on 3 April 2006, which announced that filming on the series had begun in Hungary and also announced further casting.

On Thursday 23 November 2006, the BBC confirmed that the programme had been renewed for a second series, to be shown in 2007. Filming began in March 2007, and the first episode of the second series aired at 7:30pm on Saturday 6 October 2007.

Lucy Griffiths, who played Marian, left at the end of the show's second series, although she made a brief appearance at the conclusion of the third series.

Joining the cast for the third series are Joanne Froggatt, as a character named "Kate", a Locksley villager, Lara Pulver, as Guy of Gisborne's sister Isabella, David Harewood as Friar Tuck and Toby Stephens as Prince John ,and Clive Standen as Archer, Robin's half brother. On 7 August 2008 it was announced that Jonas Armstrong would be leaving the programme at the conclusion of the third series, in "an explosive and nail-biting finale."

In January 2009, the writer Sally Wainwright told The Stage entertainment industry newspaper that she had been asked to oversee a creative revamp of the programme for its fourth series. The BBC confirmed to the paper that she had been asked to work on ideas for the show, but despite this, the fourth season was not commissioned.

The majority of the main characters in Robin Hood are based on the English folk tale of the same name. The show's main character is Robin Hood (Jonas Armstrong), who has returned to England after five years fighting in the Third Crusade as part of the King's Guard. He is shocked to find out how the sheriff is running Nottingham upon his return. Robin is made an outlaw, and takes it upon himself to steal from the rich, to feed the poor along with his gang, which consists of his best friend Much (Sam Troughton); two young men he saved from hanging, Will Scarlett (Harry Lloyd) and Allan A Dale (Joe Armstrong); the ex-leader of another gang, Little John (Gordon Kennedy); and another young man named Roy (William Beck), who is killed in episode 4, and replaced in episode 5 by Djaq (Anjali Jay), a Saracen girl hiding under the alias of her dead brother. Robin is pleased to find that Lady Marian (Lucy Griffiths) is still unmarried. Their relationship becomes romantic on several occasions, however she is trapped by the hold that Sir Guy of Gisborne (Richard Armitage) has over her. Guy is the sheriff's second-in-command, and is in love with Marian. He often puts her in difficult situations where she has to be with him to help the people she loves. The primary villain is the Sheriff of Nottingham (Keith Allen), who plots to kill King Richard(played by Steven Waddington in the final episode of series 2) with the help of Gisborne and the black knights. He is constantly trying to capture Robin and the rest of the outlaws, for continuously stopping his scheme to take over England. At the end of the second series Guy of Gisborne kills Marian, and Djaq and Will decide to stay in the Holy Land.

The third series staggered the entry of a group of new characters across the series and only Robin appeared in all thirteen episodes. As the series opens, ight: normal;">Tuck (David Harewood), a spiritual preacher returning to England, and Kate (Joanne Froggatt), a Locksley villager, are introduced; both soon becoming part of Robin's gang. Isabella (Lara Pulver), Gisborne's younger sister who is running from an abusive husband arrives soon after and starts a secret relationship with Robin. Her link to the castle through Gisborne is used by the gang while she plots revenge against her brother, but her thirst for independence, power and vengeance soon leads her to become a ruthless sheriff and a sworn enemy of the gang. (Toby Stephens) appears as Prince John in three episodes mid-series, successfully exploiting the rift between Gisborne and the sheriff, leading to the latter's supposed death at Gisborne's hand. Gisborne is briefly made sheriff by the Prince before Isabella uses her influence to replace him, leaving Gisborne without power or influence, and following the death of a young villager with whom he was briefly imprisoned, seeking revenge. This opens the door to a liaison with Robin and sets up the tenth episode of the series, told largely through flashbacks, which revisits Robin and Gisborne's history. It features Dean Lennox Kelly, Sophie Winkleman,Paul Hilton and Ian Reddington as Robin's father, Gisborne's parents and another past Locksley villager respectively, and reveals the existence of Archer (played by Clive Standen from episode 11), the illegitimate child of Robin's father and Gisborne's mother, who Robin's dying father begs them to find. Archer is Robin's equal with a bow and arrow, and this coupled with his biological ties to Robin, Gisborne and Isabella led to speculation that he was set to take over the programme's lead role following Jonas Armstrong's departure.^[16][17][18] Having found Archer, Gisborne and Robin return to Nottingham with a tentative alliance formed, setting up the two-part series finale. Allan is killed in episode 12, but appears briefly as a corpse (uncredited) in the series final episode. In the final confrontation that ends the series, Gisborne is killed in a sword fight defending the castle, and Robin poisoned, ultimately leading to his death. As he dies, Marian makes a brief appearance as a spirit with whom he reunites. The sheriff and Isabella are caught in the explosion of Nottingham Castle, caused by Robin's last act of firing a flaming arrow into the Byzantine fire stored in the castle.
