It鈥檚 common knowledge that there are 50 states in the United States of America鈥攁nd you might even be able to name them all鈥攂ut did you know that four of them are technically considered commonwealths?
You might even live in one of these four and not even know it. Read on to find out if you do, and if so, what that means for how your state鈥攕orry, your commonwealth鈥攊s governed. We鈥檒l also try to clear up the state of confusion by sharing our wealth of knowledge about what commonwealth means in other contexts.
鈿� Quick summary
Pennsylvania, Kentucky, Virginia, and Massachusetts are commonly referred to as states, but they are actually legally designated as commonwealths. But the difference is only in the name鈥攂eing a commonwealth doesn鈥檛 entail any legal or governmental differences from the other 46 states.
What does commonwealth mean?
Commonwealth has several different meanings (and it is often capitalized). It can refer to a federation of states (Australia is designated as a Commonwealth in this way), a self-governing US territory (Puerto Rico and the Northern Mariana Islands are designated as Commonwealths in this way), or an association of nations (such as what鈥檚 known as the British Commonwealth or the Commonwealth of Nations). It can also be used in more general ways, such as to refer to the body of people of a nation or any group of people united by some common interest. 颁辞尘尘辞苍飞别补濒迟丑听combines the word聽common and wealth (as in “the condition of being happy and prosperous”).
But in the context of the US and its 50 states, the word commonwealth is simply used as another word for state in the official names of four states in particular.

Which states are commonwealths?
Four US states are technically designated as commonwealths: Pennsylvania (admitted to the union December 12, 1787), Massachusetts (February 6, 1788), Virginia (June 25, 1788), and Kentucky (June 1, 1792). The first three were among the original 13 colonies (Kentucky was part of Virginia until it became the 15th state). All four use the word commonwealth in their official name: the Commonwealth of Pennsylvania, the Commonwealth of Massachusetts, the Commonwealth of Virginia, and the Commonwealth of Kentucky.
You might have noticed that we鈥檝e called the four of them states, and, frankly, so does just about everyone else鈥攊ncluding their residents. After all, we usually say that the US has 50 states (not 46 states and four commonwealths).
So what does this mean in practical terms? What sets commonwealths apart from other states?
What is the difference between a state and a commonwealth?
Other than the name, there really is no legal or governmental difference between states known as states and states known as commonwealths. The word commonwealth was simply the word chosen as the official designation of each of them as a political entity鈥攁nd the one used in official founding documents like the state constitution (it鈥檚 typically understood to imply that the commonwealth was founded through the common will of the people and for the common good). In fact, the word state is also often used in such documents without any distinction.
In addition, the states of Vermont and Delaware use both commonwealth and state in official documents.
How to use commonwealth vs. state
When it comes to Pennsylvania, Kentucky, Virginia, and Massachusetts, the word commonwealth is really only used in the context of their official names in official documents鈥攐r as a bit of good trivia. In general, all four are most commonly called states.
In other contexts, the word commonwealth may have more importance or entail a legal distinction. For example, because Puerto Rico is a Commonwealth territory of the US, its citizens are US citizens, but they do not have all the legal rights of the citizens of US states.
