Parliament-Funkadelic is a funk music collective headed by George Clinton. It specialized in the style of music known as P Funk and performed under the names Parliament and Funkadelic (two bands consisting of the same members, recording for different labels), but also in a score of offshoot groups and solo ventures. Recording under myriad names, this group had thirteen Top Ten hits in the U.S. R&B music charts between 1967 and 1983, including six number one hits in the R&B Charts. They were inducted to the Rock and Roll Hall of Fame in 1997. Collectively the group has existed under various names since the 1960s and has been known for top-notch musicianship, politically charged lyrics, outlandish concept albums and memorable live performances.

Today the band tours as either "George Clinton and the P-Funk All-Stars" or "George Clinton and Parliament-Funkadelic". Some former members of Parliament perform under the name "Original P."

The etymology of the term "P-Funk" is subject to multiple interpretations. It has been identified typically as an abbreviation of "Parliament-Funkadelic". Another suggested definition is "Plainfield Funk", referring to Plainfield, New Jersey, the hometown of the band's original line-up. The liner notes of CD versions of the Motor Booty Affair album suggest that the 'P' stands for 'Pure'. It has also been suggested that it is an abbreviation of "Psychedelic Funk". The breakout popularity of Parliament-Funkadelic elevated the status of "P-Funk" to describe what is now considered to be a genre of music in its own right. Fans of this genre of music often refer to it as "The P".
