States That Start With O

States that start with O: 3 US states do, Ohio, Oklahoma, Oregon. The table gives each state's postal abbreviation, capital and largest cities, and the lists below show state capitals and US cities that start with O.

Three states begin with O, and they make a neat set for young learners because each is short and easy to say. Ohio sits in the Midwest, Oklahoma lies in the southern plains, and Oregon faces the Pacific Ocean in the Northwest.

Two of the three are simple on capitals. Columbus is both the capital and the biggest city in Ohio, and Oklahoma City holds both roles in Oklahoma. Oregon is the odd one: Salem is the capital, while Portland is the largest city. Ohio is also a fun word to spell, with an O at each end.
