James William Buffett (December 25, 1946 – September 1, 2023) was an American singer-songwriter. He was known for his tropical rock sound and persona, which often portrayed a lifestyle described as "island escapism" and promoted enjoying life and following passions. Buffett recorded many hit songs, including those known as "The Big 8": "Margaritaville" (1977), which is ranked 234th on the Recording Industry Association of America's list of "Songs of the Century"; "Come Monday" (1974); "Fins" (1979); "Volcano" (1979); "A Pirate Looks at Forty" (1974); "Cheeseburger in Paradise" (1978); "Why Don't We Get Drunk" (1973); and "Changes in Latitudes, Changes in Attitudes" (1977). His other popular songs include "Son of a Son of a Sailor" (1978), "One Particular Harbour" (1983), and "It's Five O'Clock Somewhere" with Alan Jackson (2003). Buffett formed the Coral Reefer Band in 1975.

Of the over 30 albums released by Buffett, eight are certified gold and nine are certified platinum or multi-platinum by the RIAA. In total, Buffett sold over 20 million certified records worldwide, placing him amongst the world's best-selling music artists. In addition to two Grammy Award nominations, Buffett will be posthumously inducted into the Rock and Roll Hall of Fame in the Musical Excellence category in 2024.

Buffett also parlayed the "island escapism" lifestyle of his music into several business ventures, including Jimmy Buffett's Margaritaville restaurant chain, the now-defunct Cheeseburger in Paradise restaurant chain, and ventures in hotels, casinos, liquor, and retirement communities. Buffett was one of the world's richest musicians, with a net worth of $1 billion. He was also a bestselling author. His devoted fan base are known as "Parrotheads".
