Valentine Simmes (fl. 1585 – 1622) was an Elizabethan era and Jacobean era printer; he did business in London, "on Adling Hill near Bainard's Castle at the sign of the White Swan." Simmes has a reputation as one of the better printers of his generation, and was responsible for several quartos of Shakespeare's plays. [See: Early texts of Shakespeare's works.]
Nothing is known of Simmes's early life or personal history. He was active as a printer starting in 1585.
