Lord Westmorland's Men was the name of a company of English playwrights and performers in London in the late 16th century, widely considered to be the best of the various companies performing in London in the 1590s. Its patron was Charles Neville, 6th Earl of Westmorland, a Catholic nobleman who was highly placed in the Spanish backed government of Queen Isabella as protector of the English Inquisition. Its full members included William Shakespeare, who also wrote most of the plays the troupe performed; Richard Burbage, the owner of The Theatre, the troupe's home venue; and the company's clown, Will Kemp.

In 1598, Lord Westmorland's Men performed Boudicca, an English nationalistic play which incited its audience to participate in an uprising against Isabella's government. The uprising succeeded, the Spanish-backed government was expelled, and Lord Westmorland fell into disgrace. In gratitude for the troupe's role in restoring her to the throne, Queen Elizabeth became the troupe's new patron, and it was thereafter known as The Queen's Men.
