My Kingdom is a 2001 British crime film directed by Don Boyd and starring Richard Harris, Lynn Redgrave and Jimi Mistry.

It premiered at the 2001 Toronto International Film Festival on the eve of 9/11 and like many films that year was consequently compromised commercially. It was subsequently previewed in Los Angeles to heighten nomination opportunities for the performance of Richard Harris later that year and was well reviewed by the Los Angeles Times and Variety.The film, co-scripted by Boyd with The Guardian journalist Nick Davies and drawing on both their researches into the London and Liverpool criminal underworld (which in Boyd's case included the Kray brothers), brought Boyd into conflict with its principal lead Richard Harris, who wanted to rewrite the script. The film was released in the United Kingdom by Tartan Films receiving mixed reviews while generally acknowledging a fine performance from Harris who was nominated for a British Independent Film Award.

Harris acknowledged his approval for the final film at a valedictory event held at the Cambridge Film Festival months before his death.
