Thomas Chittenden, Governor of the Vermont Republic, and first Governor of the State of Vermont (born 1730)

Thomas Chittenden was an American politician from Vermont, who was a leader of the territory for nearly two decades. He was the state's first and third governor, serving from 1778 to 1789—when it was a largely unrecognized independent state called the Vermont Republic—and again from 1790 until his death. Vermont was admitted to the Union in 1791 as its 14th state.

The Vermont Republic, officially known at the time as the State of Vermont, was an independent state in New England that existed from January 15, 1777, to March 4, 1791. The state was founded in January 1777, when delegates from 28 towns met and declared independence from the jurisdictions and land claims of the British colonies of Quebec, New Hampshire, and New York. The republic remained in existence for the next fourteen years, albeit without diplomatic recognition from any foreign power. On March 4, 1791, it was admitted into the United States as the State of Vermont, with the constitution and laws of the independent state continuing in effect after admission.

The governor of Vermont is the head of government of the U.S. state of Vermont. The officeholder is elected in even-numbered years by direct voting for a term of two years. Vermont and bordering New Hampshire are the only states to hold gubernatorial elections every two years, instead of every four as in the other 48 U.S. states.
