The culture of the United Kingdom is the pattern of human activity and symbolism associated with the United Kingdom and its people. It is influenced by the UK's history as a developed island country, a liberal democracy and a major power, its predominantly Christian religious life, and its composition of four countries—England, Northern Ireland, Scotland and Wales—each of which has distinct customs, cultures and symbolism. The wider culture of Europe has also influenced British culture, and Humanism, Protestantism and representative democracy developed from broader Western culture.

British literature, music, cinema, art, theatre, comedy, media, television, philosophy, architecture and education are influential and respected across the world. The United Kingdom is also prominent in science and technology, producing world-leading scientists (e.g. Isaac Newton and Charles Darwin) and inventions. Sport is an important part of British culture; numerous sports originated in the country, including football. The UK has been described as a "cultural superpower", and London has been described as a world cultural capital.
