The Passionate Pilgrim (1599) is an anthology of 20 poems collected and published by William Jaggard that were attributed to "W. Shakespeare" on the title page, only five of which are considered authentically Shakespearean. These are two sonnets, later to be published in the 1609 collection of Shakespeare's Sonnets, and three poems extracted from the play Love's Labour's Lost. Internal and external evidence contradicts the title page's attribution to Shakespeare. Five were attributed to other poets during his lifetime, and two were published in other collections anonymously. While most critics disqualify the rest as not Shakespearean on stylistic grounds, stylometric analysis by Ward Elliott and Robert Valenza put two blocks of the poems (4, 6, 7 and 9, and 10, 12, 13 and 15) within Shakespeare's stylistic boundaries.

William Shakespeare (26 April 1564 – 23 April 1616) was an English playwright, poet, and actor, widely regarded as the greatest writer in the English language and the world's greatest dramatist. He is often called England's national poet and the "Bard of Avon" (or simply "the Bard"). 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. They also continue to be studied and reinterpreted.
