Admiral of the Blue Edward Boscawen, PC was a British admiral in the Royal Navy and Member of Parliament for the borough of Truro, Cornwall, England. He is known principally for his various naval commands during the 18th century and the engagements that he won, including the siege of Louisburg in 1758 and Battle of Lagos in 1759. He is also remembered as the officer who signed the warrant authorising the execution of Admiral John Byng in 1757, for failing to engage the enemy at the Battle of Minorca (1756). In his political role, he served as a Member of Parliament for Truro from 1742 until his death although due to almost constant naval employment he seems not to have been particularly active. He also served as one of the Lords Commissioners of the Admiralty on the Board of Admiralty from 1751 and as a member of the Privy Council from 1758 until his death in 1761.

The siege of Louisbourg was a pivotal operation of the Seven Years' War in 1758 that ended the French colonial era in Atlantic Canada and led to the subsequent British campaign to capture Quebec in 1759 and the remainder of French North America the following year.
