"Paul is dead" is an urban legend and conspiracy theory alleging that English pop musician Paul McCartney of the Beatles died in 1966 and was secretly replaced by a look-alike. The rumour began circulating in 1966, gaining broad popularity in September 1969 following reports on American college campuses.

Sir James Paul McCartney is an English singer, songwriter and musician who gained worldwide fame with the Beatles, for whom he played bass guitar and shared primary songwriting and lead vocal duties with John Lennon. One of the most successful composers and performers of all time, McCartney is known for his melodic approach to bass-playing, versatile and wide tenor vocal range, and musical eclecticism, exploring genres ranging from pre–rock and roll pop to classical, ballads, and electronica.
