Count: 0 — There are no official U.S. state capitals that start with the letter U. This list targets formal state capitals (the official seats of state government) and their populations; interestingly, only one U.S. state begins with U (Utah), and its capital is Salt Lake City, so the letter U simply does not appear as the initial letter of any state capital.

Understand why the search returns no results. Limit the scope to 50 official state capitals and you have a small, fixed set of place names created from many languages and historical sources; the letter U is uncommon as a first letter in those names. Use authoritative references such as the U.S. Census Bureau (2020 Census and the latest population estimates) and state government websites to verify official capital names and populations. Check Washington, D.C., and U.S. territorial capitals separately — none of them begin with U either.

Consider near matches and alternatives. Cities that begin with U exist in the United States (for example, Utica or Union), but they are not state capitals. For useful variants, consult the A–Z master index of state capitals, lists of capitals by population, or lists of territorial and municipal seats if you want broader coverage beyond official state capitals.
