William Henry Ireland (1775–1835) was an English forger of would-be Shakespearean documents and plays. He is less well known as a poet, writer of gothic novels and histories. Although he was apparently christened William-Henry, he was known as Samuel through much of his life, and many sources list his name as Samuel William Henry Ireland.

Samuel Ireland, English author and engraver, is best remembered today as the chief victim of the Ireland Shakespeare forgeries created by his son, William Henry Ireland.
