Lord William Beauclerk (1766-1825) was the son of Aubrey Beauclerk, 5th Duke of St. Albans, and was the fourth of his parents' seven children. He was a great-great-grandson of King Charles II by Charles's mistress Nell Gwyn.

William's brother Aubrey had originally inherited the title of duke, becoming the 6th Duke. Aubrey died in 1815 and left the title to his son (also named Aubrey) who died within the year, still in infancy. The title then passed back to Uncle William, who thus became the 8th Duke of St. Albans.

In 1791, William married Charlotte Thelwell, who died in 1797. He married again in 1799 to Maria Janetta Nelthorpe who gave him thirteen children.

In 1825, William died at age 58. William Aubrey de Vere Beauclerk, his firstborn son, inherited as the 9th Duke of St. Albans.
