Count: 0 — In the official list of U.S. state capitals (and including Washington, D.C., and U.S. territorial capitals), there are no capitals that begin with the letter K. This is notable because two U.S. states begin with K (Kansas and Kentucky) and several large American cities start with K (Kansas City, Knoxville, Kalamazoo), yet none of these are seats of state government.

Understand that state capital names reflect historical settlement patterns, Native American words, and colonial languages, and those naming traditions rarely produced initial K sounds for the towns chosen as capitals. Rely on authoritative sources such as official state government lists and U.S. Census population estimates when compiling capital lists; those sources confirm the absence of K-starting state capitals.

Note related categories that do exist. Look at country capitals that start with K (for example, Kabul, Kampala, Kingston) or at U.S. cities that begin with K but are not capitals (Kansas City, Knoxville, Kalamazoo). Consult a master A–Z index of U.S. capitals for accurate, alphabetical results and population data by year.
