Island of Circles is a tribute album to singer-songwriter Donovan that was released on June 26, 1992 by Nettwerk. The title song "Island of Circles" is provided by Donovan himself. Along with Donovan's contemporaneous box set collection Troubadour: The Definitive Collection 1964–1976, the album contributed to a resurgence of interest in Donovan's music in the early 1990s, after he had been deemed unfashionable and out of step with changing musical tastes in the 1970s. The song "Island of Circles" was recorded again for the 2004 Donovan album Brother Sun, Sister Moon.
