Chester Simon Kallman was an American poet, librettist, and translator, best known for his collaborations with longtime partner W H Auden and Igor Stravinsky.
Kallman was born in Brooklyn. He received his BA at Brooklyn College and his MA at the University of Michigan. He published three collections of poems, Storm at Castelfranco (1956), Absent and Present (1963), and The Sense of Occasion (1971). He lived most of his adult life in New York, spending his summers in Italy from 1948 through 1957 and in Austria from 1958 through 1974. He moved his winter home from New York to Athens in 1963.

Kallman was the sole author of the libretto of The Tuscan Players for Carlos Chávez (1953, first performed in 1957 as Panfilo and Lauretta).
He and Auden collaborated on a number of libretto translations, notably The Magic Flute (1956) and Don Giovanni (1961). Kallman also translated Verdi's Falstaff (1954), Monteverdi's The Coronation of Poppea (1954) and many other operas.
