"Lady D'Arbanville" is a song written and recorded by Cat Stevens and released in April 1970. It subsequently appeared on his third album, Mona Bone Jakon, released later that year. It was his first single released after signing a contract with Island Records, with the encouragement of his new producer, Paul Samwell-Smith, fostering a folk rock direction. "Lady D'Arbanville" has a madrigal sound, and was written about Stevens' former girlfriend, Patti D'Arbanville, metaphorically laying her to rest.
