May Day is an early 17th-century stage play, a comedy written by George Chapman that was first published in 1611.
May Day enters the historical record when it was printed in a quarto edition by the stationer John Browne. This was the sole edition of the play prior to the 19th century. The title page of the 1611 quarto identifies Chapman as the author, and states that the play was acted at the Blackfriars Theatre, meaning it was performed by the Children of the Blackfriars, the troupe of boy actors that staged most of Chapman's early comedies.
