County Maps US

All 3,144 US counties, A to Z

Every county and county-equivalent in the 50 states and the District of Columbia, listed by name. Pick a letter, or jump straight to a state. Each entry carries its population, land area and density, and names its state, because 442 county names are used more than once.

By first letter

25 letters are in use. No county name begins with X, so there is no page for it.

The same name, different places

Of 3,144 counties there are only 1,838 distinct names. 442 of those names belong to more than one county, which is why searching for a county by name alone will usually find the wrong one. These are the most reused.
