William Marshal, 1st Earl of Pembroke (1146 or 1147 – 14 May 1219), also called William the Marshal (Norman French: Williame le Mareschal), was an Anglo-Norman soldier and statesman. He served five English kings – Henry II, his sons The "Young King" Henry, Richard I, John, and John's son Henry III.

Knighted in 1166, he spent his younger years as a knight errant and a successful tournament competitor; Stephen Langton eulogized him as the "best knight that ever lived." In 1189, he received the title of Earl of Pembroke through marriage during the second creation of the Pembroke Earldom. In 1216, he was appointed protector for the nine-year-old Henry III, and regent of the kingdom.

Before him, his father's family held a hereditary title of Marshal to the king, which by his father's time had become recognized as a chief or master Marshalcy, involving management over other Marshals and functionaries. William became known as 'the Marshal', although by his time much of the function was actually delegated to more specialized representatives (as happened with other functions in the King's household). Because he was an Earl, and also known as the Marshal, the term "Earl Marshal" was commonly used and this later became an established hereditary title in the English Peerage.

William's father, John Marshal, supported King Stephen when he took the throne in 1135, but in about 1139 he changed sides to back the Empress Matilda in the civil war of succession between her and Stephen which led to the collapse of England into "the Anarchy".
