Dragonfly is the second studio album by English band Strawbs. It contains the lengthy and rather progressive ballad "The Vision of the Lady of the Lake" describing the hardships of a boatman who encounters and battles a variety of mystical creatures on a lake, with a sword that was given to him by the lady of the lake. The album marked the first collaboration of Rick Wakeman with the band, though he only played on one song on this album, piano on The Vision of the Lady of the Lake; he eventually joined them on their next album, Just a Collection of Antiques and Curios, in 1970. Tony Visconti also played flute on two other songs.
