William Paget, 4th Baron Paget of Beaudesert (1572 – 29 August 1629) was an English peer and colonist born in Beaudesert House, Staffordshire, England to Thomas Paget, 3rd Baron Paget and Nazareth Newton. He was a descendent of William Paget, 1st Baron Paget. William's father had been stripped of his title after fleeing to Spain, as a result of his Catholicism. England had recently become a Protestant state when Henry VIII had separated the Church of England and placed himself at its head. Europe was ablaze with conflicts between Catholics and Protestants. England's old enemy, France, was in the midst of its Religious Wars, which saw the St. Bartholomew's Day massacre in the year in which William was born.

Life William, a Protestant, applied himself vigorously to England's interests, taking part in a 1596 expedition to Calais. He never earned the favour of Queen Elizabeth I, but the family title and lands were restored upon him by her Scottish heir, King James I, in 1605. In 1612 he became an adventurer of the Virginia Company. The Company had been created under Royal Charter to colonise North America as a merchant venture. It founded its first settlement, Jamestown, in 1607. That colony fared badly in its first years, and a fleet sent to relieve it in 1609 was broken up by a hurricane, with the Company's flagship, the Sea Venture, lost on the reefs of Bermuda. This began England's claim to, and the permanent settlement of, Bermuda, and the Virginia Company's Third Charter extended the limits of Virginia far enough out to sea to encompass Bermuda, which was also known as Virgineola. The first intended settlers arrived in 1612, to join the remaining survivors of the Sea Venture. Ever since, the colony (now called an Overseas Territory) has had two official names, Bermuda, and The Somers Isles. In 1615, a second company was created by the shareholders of the Virginia Company. Called the Somers Isles Company, this administered Bermuda until 1684. Eight of Bermuda's nine parishes (originally called tribes) were commercial land, and named for major shareholders of the Company. Paget Parish, in the centre of Bermuda, was named for William Paget in 1617. The coat of arms of the parish is identical to that of the Baron Paget de Beaudesert. William Paget died in 1629, and was buried in West Drayton, in Middlesex.
