The Merry Wives of Windsor or Sir John Falstaff and the Merry Wives of Windsor is a comedy by William Shakespeare first published in 1602, though believed to have been written in or before 1597. The Windsor of the play's title is a reference to the town of Windsor, also the location of Windsor Castle in Berkshire, England. Though nominally set in the reign of Henry IV or early in the reign of Henry V, the play makes no pretence to exist outside contemporary Elizabethan-era English middle-class life. It features the character Sir John Falstaff, the fat knight who had previously been featured in Henry IV, Part 1 and Part 2. It has been adapted for the opera at least ten times. The play is one of Shakespeare's lesser-regarded works among literary critics. Tradition has it that The Merry Wives of Windsor was written at the request of Queen Elizabeth I. After watching Henry IV Part I, she asked Shakespeare to write a play depicting Falstaff in love.

In English folklore, Herne the Hunter is a ghost associated with Windsor Forest and Great Park in the English county of Berkshire. He is said to have antlers growing from his head, ride a horse, torment cattle, and rattle chains. The earliest mention of Herne comes from William Shakespeare's 1597 play The Merry Wives of Windsor, and it is impossible to know how accurately or to what degree Shakespeare may have incorporated a real local legend into his work, though there have been several later attempts to connect Herne to historical figures, pagan deities, or ancient archetypes.
