The Edwardian era or Edwardian period in the United Kingdom is the period covering the reign of King Edward VII, 1901 to 1910.

The death of Queen Victoria in January 1901 and the succession of her son Edward marked the end of the Victorian era. While Victoria had shunned society, Edward was the leader of a fashionable elite that set a style influenced by the art and fashions of Continental Europe—perhaps because of the King's fondness for travel. The era was marked by significant shifts in politics as sections of society that had been largely excluded from wielding power in the past, such as common labourers and women, became increasingly politicised.

The Edwardian period is sometimes extended beyond Edward's death in 1910 to include the years up to the sinking of the RMS Titanic in 1912, the start of World War I in 1914, the end of hostilities with Germany in 1918, or the signing of the Treaty of Versailles in 1919.

The Edwardian era was a period during which the British class system was very rigid. Economic and social changes created an environment in which there was more social mobility. Such changes included rising interest in socialism, attention to the plight of the poor and the status of women, including the issue of women's suffrage, together with increased economic opportunities as a result of rapid industrialisation. These changes were to be hastened in the aftermath of the First World War.
