Years and Years is a dystopian science fiction drama television miniseries written by Russell T Davies. Taking place between 2019 and 2034, the six-part series follows the lives of the Lyons family, who witness increasingly tumultuous global affairs and the rise to power of Vivienne Rook, an outspoken British celebrity businesswoman turned populist politician whose controversial opinions divide the nation. The series was a co-production between the BBC and HBO, and premiered on BBC One on 14 May 2019 and on HBO on 24 June 2019. Years and Years stars Emma Thompson as Rook, alongside Russell Tovey, Rory Kinnear, T'Nia Miller, Ruth Madeley, Anne Reid, and Jessica Hynes as the Lyons family.

The series was directed by Simon Cellan Jones (episodes 1–4) and Lisa Mulcahy (episodes 5–6), with Davies, Cellan Jones, Michaela Fereday, Lucy Richer, and Nicola Shindler serving as executive producers. It received praise for its writing, characterisation, and exploration of modern political anxieties in a dystopian future.
