Changing Horses is the fifth album by the Scottish psychedelic folk group, the Incredible String Band (ISB), and was released in November 1969 on Elektra Records. The album saw the group continuing their use of unique instruments while integrating a standard musical structure. In addition, the album is seen as a transitional period in which the ISB shifted in musical textures, including early utilization of electric-based instruments.

The Incredible String Band were a British psychedelic folk band formed by Clive Palmer, Robin Williamson and Mike Heron in Edinburgh in 1966. The band built a considerable following, especially in the British counterculture, notably with their albums The 5000 Spirits or the Layers of the Onion (1967), The Hangman's Beautiful Daughter (1968), and Wee Tam and the Big Huge (1968). They became pioneers in psychedelic folk and, through integrating a wide variety of traditional music forms and instruments, in the development of world music.
