State Capitals That Aren't the Biggest City

The most common mistakes on this quiz come from states where people instinctively name the largest or most famous city instead of the actual capital.

  • Kentucky — Frankfort, not Louisville or Lexington
  • Nevada — Carson City, not Las Vegas or Reno
  • Illinois — Springfield, not Chicago
  • New York — Albany, not New York City
  • Pennsylvania — Harrisburg, not Philadelphia or Pittsburgh
  • Michigan — Lansing, not Detroit or Grand Rapids
  • Maryland — Annapolis, not Baltimore
  • New Mexico — Santa Fe, not Albuquerque
  • Montana — Helena, not Billings
  • Vermont — Montpelier, not Burlington

State Capitals by the Numbers

A few facts worth knowing before or after the quiz:

  • Most populous capital: Phoenix, Arizona — over 1.6 million residents.
  • Least populous capital: Montpelier, Vermont — fewer than 8,000 residents.
  • Largest capital by area: Juneau, Alaska — bigger than Rhode Island.
  • Smallest capital by area: Annapolis, Maryland.
  • Oldest capital: Santa Fe, New Mexico — founded in 1610.
  • Only capital unreachable by road: Juneau, Alaska — accessible only by air or sea.

Frequently Asked Questions

Does this quiz cover all 50 state capitals?
Yes, every U.S. state is included. Washington, D.C. is not in the quiz — it's the federal capital, not a state capital.
Which state capitals are the hardest to remember?
The trickiest ones are usually where the capital is not the largest or most famous city: Frankfort (Kentucky), Carson City (Nevada), Springfield (Illinois), Albany (New York), and Montpelier (Vermont) are the most commonly missed.
Are the questions different each time I play?
Yes. Both the question order and the answer choices shuffle every round, so replaying the quiz is useful for practice.
What is the most populous U.S. state capital?
Phoenix, Arizona, with over 1.6 million residents. It's one of the few cases where the state capital is also the largest city in the state by a wide margin.
What is the least populous U.S. state capital?
Montpelier, Vermont, with fewer than 8,000 residents — the smallest state capital in the country by population.
Which state capital can't be reached by road?
Juneau, Alaska. It's surrounded by water and mountains, so you can only get there by plane or boat.
Is this good for studying for a geography test?
Yes. The randomized format and instant feedback after each answer make it a practical study tool. The quiz also notes when the capital is not the state's largest city, which is where most mistakes happen.
Do I need to sign up to play?
No. The quiz is free and starts immediately, no account required.
