- As music
The poem was adapted by the folk duo Simon & Garfunkel for their song "Richard Cory", which has also been performed by Them, Van Morrison, and The Chicago Loop. The song has been played live by Paul McCartney & Wings, Denny Laine singing lead. The Simon & Garfunkel version of the song's ending differs from the poem in that the speaker still wishes he "could be Richard Cory", even after Cory has killed himself. The Latter-day Saint folk trio "3Ds" performed a musical adaptation of the poem in their 1970s album Rhyme Rhythm and Reason.
The Jamaican singer Ken Boothe performed a version of the Paul Simon song in an early reggae style for his 1968 album More of Ken Boothe. It was recorded in the famous Studio One and produced by C. S. Dodd.
The Punk band The Menzingers wrote a song titled "Richard Coury" which was inspired by the poem. The difference in spelling from Cory to Coury is because the band has a personal friend whose last name is Coury.
The American composer John Duke wrote Three Poems by Edwin Arlington Robinson, which includes the full text of the poem Richard Cory.
The American Oi band Youngblood did a version of the poem set to music written by the band.
A. R. Gurney wrote a play based on the poem, also titled Richard Cory. The play, which is presented with a nonlinear timeline, suggests the reasons Cory killed himself, including family problems and changing views on humanity.
Carolyn Mullen wrote a short story titled "Poetic Justice" which, via a surprise ending, turns out to be an "alternative history" version of "Richard Cory". Edwin Arlington Robinson appears as a character in the story, which is included in The Rich and the Dead, a 2011 short-story anthology.
American humorist Garrison Keillor wrote a variation of the poem for the Introduction to his The Book of Guys (1993), which suggested a very direct source of Cory's unhappiness.
