The Great San Bernardino Birthday Party & Other Excursions is an album by American fingerstyle guitarist and composer John Fahey, released in 1966. The cover simply labels the album Guitar Vol. 4 (it was his fourth release on his own Takoma label, but his fifth album) while the liner notes label it The Great San Bernardino Birthday Party & Other Excursions. The title never appeared on the record labels themselves. It marked the beginning of Fahey's interest in his recording of experimental soundscapes and sound effects. Despite Fahey's distaste for the 1960s counterculture, it is his release most often referred to as psychedelic.
