Arthur or the Decline and Fall of the British Empire, often referred to simply as Arthur, is the seventh studio album by the English rock band the Kinks, released on 10 October 1969. It was the first Kinks album to feature bassist John Dalton, who replaced Pete Quaife. Kinks frontman Ray Davies constructed the concept album as the soundtrack to a Granada Television play and developed the storyline with novelist Julian Mitchell; the television programme was never produced. The rough plot revolved around Arthur Morgan, a carpet-layer, who was based on Ray and guitarist Dave Davies' brother-in-law Arthur Anning. A stereo version was released internationally with a mono version being released in the UK, but not in the US.

The Kinks were an English rock band formed in London in 1963 by brothers Ray and Dave Davies. They are regarded as one of the most influential rock bands of the 1960s. The band emerged during the height of British rhythm and blues and Merseybeat, and were briefly part of the British Invasion of the United States until their touring ban in 1965. Their third single, the Ray Davies-penned "You Really Got Me", became an international hit, topping the charts in the United Kingdom and reaching the Top 10 in the United States.
