The Webster-Ashburton Treaty, signed August 9, 1842, settled the dispute over the location of the Maine-New Brunswick border between the United States and Canada as well as the location of the border in the westward frontier up to the Rocky Mountains. It also called for a final end to the slave trade on the high seas, to be enforced by both signatories.

The agreement was signed by United States Secretary of State Daniel Webster and United Kingdom Privy Council member Alexander Baring, Lord Ashburton.

The treaty resolved issues that had led to the Aroostook War as well as the Caroline Affair. The Creole case was passed over by both nations.
