The "Pearl Poet", or the "Gawain Poet", is the name given to the author of Pearl, an alliterative poem written in 14th-century Middle English. Its author appears also to have written the poems Sir Gawain and the Green Knight, Patience, and Cleanness; some scholars suggest the author may also have composed Saint Erkenwald. Save for the latter (found in BL-MS Harley 2250), all these works are known from a single surviving manuscript, the British Library holding Cotton Nero A.x. This body of work includes some of the greatest poetry written in Middle English.
