The Marquis of Kensington was a British studio project from the end of the 1960s. It consisted of Robert Wace, then manager of The Kinks, and the record producer Mike Leander (1941–1996).^[1] While the project's vocals are Wace's, Leander was featured on the single covers. Wace wanted to remain incognito.

The duo released three singles:

• "The Changing Of The Guard" / "Reverse Thrust" (instrumental) (May 1967)^[1]
• "Sister Marie" / "Flash" (instrumental) (Feb 1968)
• "It Might As Well Rain Until September" / "Folks In The City" (Nov 1968)

In 1970, a cover of "Flash" by Italian instrumentalist Marco Battani reached number 11 in the Dutch Top 40.^[2] He had released the song as The Duke of Burlington.
