Thomas McKean (1734 - 1817) was an American lawyer, judge, and statesman who played a prominent role during the American Revolution and in the early years of the United States. Born in Pennsylvania, McKean was a leading figure in both colonial and revolutionary politics. He served as a delegate to the Continental Congress, where he signed the Declaration of Independence, and was one of the few to sign both the Declaration and the Articles of Confederation.

McKean was also a key figure in Pennsylvania's political life, serving as the state's governor from 1799 to 1808. Before his governorship, he had held various other political positions, including president of the Continental Congress in 1781 and chief justice of Pennsylvania. Throughout his career, McKean was an advocate for strong central government and played a significant role in shaping Pennsylvania's legal and political systems.

After his public service, McKean retired to a life of relative quiet but remained involved in local affairs. He passed away in 1817, leaving behind a legacy as a committed patriot and influential leader during the nation's formative years.
