No U.S. State Has a Capital Named Oslo—That's Norway's Capital

There is no U.S. state with a capital called Oslo. Oslo is the capital city of Norway, located in Scandinavia.

U.S. state capitals are all distinctively American names (e.g., Sacramento, Austin, Boston, Atlanta). Some share names with foreign cities (Paris, Texas; London, Kentucky; Moscow, Idaho), but none are named Oslo.

This confusion may arise from Norwegian immigration to the Upper Midwest (Minnesota, North Dakota, Wisconsin), where towns like Oslo, Minnesota exist—but it's a small unincorporated community, not a state capital.
