In 2001, the alternative rock band They Might Be Giants wrote and recorded a song called "Robert Lowell" which uses Lowell's poem "Memories of West Street and Lepke" as the basis for the lyrics.
Lowell's friendship with Elizabeth Bishop was the subject of the play Dear Elizabeth by Sarah Ruhl which was first performed at the Yale Repertory Theater in 2012. Ruhl used Words in Air: The Complete Correspondence Between Elizabeth Bishop and Robert Lowell as the basis for her play.
Lowell was a featured subject in the 2014 HBO documentary The 50 Year Argument about The New York Review of Books which Lowell and his second wife, Elizabeth Hardwick, were both involved in founding. Although Lowell was not involved with the editing of the book review, he was a frequent contributor. Lowell is featured in voice-over, photographs, video, and Derek Walcott reads from an essay on Lowell that Walcott published in The New York Review of Books after Lowell's death.
