The Favourite is a 2018 period black comedy film directed by Yorgos Lanthimos from a screenplay by Deborah Davis and Tony McNamara, starring Olivia Colman, Emma Stone and Rachel Weisz. Set in early 18th-century Great Britain, the plot trails the relationship between cousins Abigail Masham and Sarah Churchill, Duchess of Marlborough as they vie to be court favourite of Queen Anne.

Principal photography for the British–Irish–American production took place at Hatfield House in Hertfordshire and at Hampton Court Palace, lasting from March to May 2017. The film premiered on 30 August 2018 at the 75th Venice International Film Festival, where it won the Grand Jury Prize and the Volpi Cup for Best Actress for Colman. It was released theatrically in the United States on 23 November 2018 by Fox Searchlight Pictures, and in the United Kingdom and Ireland on 1 January 2019. The film was a box office success, grossing $95 million worldwide on a production budget of $15 million.

The Favourite received widespread critical acclaim, with particular praise drawn to Lanthimos' direction and the lead actresses' performances, and it won or was nominated for numerous awards, including ten Academy Award nominations, tying Roma for the most nominations of any film at that year's ceremony. It won ten British Independent Film Awards, seven BAFTA Awards, and eight European Film Awards, and Colman won Best Actress at each of those ceremonies, as well as the Academy Awards, the Golden Globes, and others. The American Film Institute named the film one of the top ten films of 2018. Since then, it has been cited as among the best films of the 2010s and of the 21st century.
