King George's War (1744-1748) was the North American theater of the War of the Austrian Succession, fought primarily between British and French colonial forces, along with their respective Native American and colonial allies, in the regions of New England, Nova Scotia (Acadia), and New York. It was the third of the four French and Indian Wars and takes its name from King George II of Great Britain. The war ended inconclusively with the Treaty of Aix-la-Chapelle in 1748, which restored most pre-war territorial boundaries.

Historians broadly agree on the war's major events and outcomes, including the 1745 siege and capture of the French fortress of Louisbourg on Île Royale (Cape Breton Island) by a New England militia force under William Pepperrell, supported by a British naval squadron under Peter Warren. The war also saw extensive raiding along the New England-Acadia frontier and in the Mohawk Valley of New York, involving Abenaki, Mi'kmaq, and Iroquois participants alongside colonial militias. There is some continuing scholarly discussion regarding the relative weight given to colonial initiative versus imperial direction in explaining the Louisbourg expedition's success, and regarding the war's role in shaping subsequent Anglo-French colonial rivalry.

• Imperial-rivalry framing - Views the war primarily as a colonial extension of the European dynastic and imperial conflict between Britain and France, with North American events subordinate to European strategic concerns. See king-georges-war-imperial-rivalry-viewpoint.
• Colonial-autonomy framing - Emphasizes the initiative, financing, and motivations of New England colonists themselves, particularly in the Louisbourg expedition, as evidence of growing colonial self-assertion distinct from London's priorities. See king-georges-war-colonial-autonomy-viewpoint.
• Frontier and indigenous-agency framing - Centers the war's impact on and conduct by Native American nations along the New England-Acadia-New York frontier, treating Native combatants as actors pursuing their own strategic interests rather than as auxiliaries of European powers. See king-georges-war-indigenous-agency-viewpoint.

• The 1748 return of the captured fortress of Louisbourg to France under the Treaty of Aix-la-Chapelle provoked lasting resentment among New England colonists, who viewed the concession as a betrayal of colonial sacrifice for the benefit of British imperial diplomacy.
