Which is the only US state that starts with the letter P?

The only US state that begins with the letter P is Pennsylvania. It is one of the original thirteen colonies and is located in the northeastern region of the United States. Pennsylvania is known for its significant historical landmarks, including Independence Hall and the Liberty Bell, which are associated with the American Revolution and the founding of the nation.

Puerto Rico is often considered in discussions about U.S. territories, but it is not a state. It is a territory of the United States and has its own local government, but it does not have the same status as a state.

Phoenix and Portland are both cities, not states. Phoenix is the capital of Arizona, while Portland is a major city in Oregon. Therefore, they do not qualify as states starting with the letter P.
