The Portsmouth Compact was a document signed on March 7, 1638 that established the settlement of Portsmouth, which is now a town in the state of Rhode Island. It was the first document in American history that severed both political and religious ties with England.

The document was written and signed in Boston by a group of men who followed Anne Hutchinson, a banished Christian dissident from Massachusetts, seeking religious freedom apart from the governmental oversight of the Massachusetts Bay Colony by moving to Aquidneck Island to set up a new colony.
The purpose of the Portsmouth Compact was to set up a new, independent colony that was Christian in character but non-sectarian in governance. It has been called "the first instrument for governing as a true democracy."
