Coos County was created by the Territorial Legislature from parts of Umpqua and Jackson counties in 1853 and included Curry County until 1855. The county seat was Empire City until 1896 when it was moved to Coquille. Although trappers had been in the area a quarter century earlier, the first permanent settlement in present day Coos County was established at Empire City, now part of Coos Bay, by members of the Coos Bay Company in 1853. The name “Coos” derives from the Coos Tribe.

The International Port of Coos Bay, considered the best natural harbor between Puget Sound and San Francisco, is the world’s largest forest products shipping port.
