William Shakespeare (1564–1616) wrote sonnets on a variety of themes. When discussing or referring to Shakespeare's sonnets, it is almost always a reference to the 154 sonnets that were first published all together in a quarto in 1609. However, there are six additional sonnets that Shakespeare wrote and included in the plays Romeo and Juliet, Henry V and Love's Labour's Lost. There is also a partial sonnet found in the play Edward III.

William Shakespeare was an English playwright, poet, and actor. He is widely regarded as the greatest writer in the English language and the world's pre-eminent dramatist. He is often called England's national poet and the "Bard of Avon". His extant works, including collaborations, consist of some 39 plays, 154 sonnets, three long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright. Shakespeare remains arguably the most influential writer in the English language, and his works continue to be studied and reinterpreted.
