History and General Information 

Oregon’s provisional government created Clatsop County out of the northern and western portions of Twality District on June 22, 1844. It was named for the Clatsop Tribe that lived from the mouth of the Columbia River to Tillamook Head. Lewis and Clark named their winter headquarters Fort Clatsop, situated about five miles south of Astoria near the mouth of the Columbia River, for the tribe as well. 

The county is home to Astoria, Oregon’s oldest city, which was established as a fur trading post in 1811 and named after John Jacob Astor. The first U.S. Post Office west of the Rocky Mountains was established in Astoria in 1847. In 1855 the first county courthouse was completed, and the present courthouse was erected in 1904. Records show the summer resort of Seaside was founded in the early 1870s by Ben Holladay, an Oregon railroad builder. Holladay constructed the Seaside House, a famous luxury hotel for which the city was named.
