The New York Provincial Congress (1775–1777) was a revolutionary provisional government formed by colonists in 1775, during the American Revolution, as a pro-American alternative to the more conservative New York General Assembly, and as a replacement for the Committee of One Hundred. The Fourth Provincial Congress, resolving itself as the Convention of Representatives of the State of New York, adopted the first Constitution of the State of New York on April 20, 1777.

The Committee of Sixty or Committee of Observation was a committee of inspection formed in the City and County of New York, in 1775, by rebels to enforce the Continental Association, a boycott of British goods enacted by the First Continental Congress. It was the successor to the Committee of Fifty-one, which had originally called for the Congress to be held, and was replaced by the Committee of One Hundred.
