Which play was co-authored by Shakespeare and John Fletcher based on Chaucer's 'The Knight's Tale'?

The Two Noble Kinsmen was co-authored by William Shakespeare and John Fletcher and is based on Chaucer’s “The Knight’s Tale.”

The play is a Jacobean tragicomedy about Palamon and Arcite, two imprisoned Theban cousins who fall in love with Emilia and become rivals. Its main plot follows the central conflict of Chaucer’s tale, including the competing knights, the love triangle and the role of Theseus.

The Two Noble Kinsmen was probably written around 1613–1614 and was first published in 1634. Shakespeare and Fletcher were both associated with the King’s Men during this period. Modern scholarship generally accepts the play’s joint authorship, although researchers still debate which scenes or passages belong primarily to each writer.

Chaucer’s poem was not Shakespeare and Fletcher’s only influence. “The Knight’s Tale” itself draws heavily on Giovanni Boccaccio’s Italian poem Teseida. Earlier dramatic versions of the story had also been staged, including Richard Edwardes’s lost Palamon and Arcite from 1566. Among the alternatives, Henry VIII is another collaboration, but it was not based on Chaucer’s tale.
