Sunshine Superman is the third studio album by Scottish singer-songwriter Donovan. It was released in the United States on August 26, 1966, but was not released in the UK because of a contractual dispute. In June 1967, a compilation of tracks from this album and the follow-up Mellow Yellow was released as Sunshine Superman in the UK. The album featured Donovan's titular hit single, which was initially released in the US in July 1966. The album was Donovan's most successful, peaking at number 11 in the US and remaining on the Billboard Top LPs chart for six months. The 1967 UK edition peaked at number 25. The tracks from Sunshine Superman and Mellow Yellow were not mixed into stereo, with the exception of "Season of the Witch", until the 2011 2-CD deluxe edition issued by UK EMI. Whilst still incorporating folk music, these recordings mark a distinct change in Donovan's music, representing some of the first psychedelia released.

This change is partially the result of working with producer Mickie Most, whose pop sensibilities led to chart hits for many other artists at the time.
