Fare Thee Well: Celebrating 50 Years of the Grateful Dead was a series of concerts that were performed by most of the surviving members of the Grateful Dead: Bob Weir, Phil Lesh, Bill Kreutzmann and Mickey Hart, joined by Trey Anastasio, Bruce Hornsby and Jeff Chimenti, to celebrate the 50th anniversary of the Grateful Dead. The performances took place at Santa Clara's Levi Stadium on June 27 and 28, 2015 and Chicago's Soldier Field on July 3, 4 and 5, 2015. These performances marked the first time Weir, Lesh, Kreutzmann and Hart had performed together since the Dead's 2009 tour and was publicized as the final time the musicians would all perform together.

Grateful Dead was an American rock band formed in 1965 in Palo Alto, California. The band is known for its eclectic style, which fused elements of rock, blues, jazz, folk, country, bluegrass, rock and roll, gospel, reggae, and world music with psychedelia, the improvisation of their live performances, and its devoted fan base, known as "Deadheads". According to the musician and writer Lenny Kaye, the band's music "touches on ground that most other groups don't even know exists." For the range of their influences and the structure of their live performances, Grateful Dead are considered "the pioneering godfathers of the jam band world".
