Clatskanie ( /klætskɨnaɪ/) is a city in Columbia County, Oregon, United States. It was named for the Clatskanie River, which empties into the Columbia River within the city limits. The population was 1,528 at the 2000 census. The 2007 estimate is 1,710 residents.
According to some reports, the original name of this town when it was platted in 1884 was Bryantville. However, the post office in this location is shown as Clatskanie as early as December, 1871.[who?]
Clatskanie comes from a Native American word, Tlatskani. According to the Clatsop County pioneer Silas B. Smith, Tlatskani was a point in the Nehalem River that was reached from the Columbia River by way of the Youngs River or by way of the Clatskanie River. The native inhabitants, who were not in the habit of naming streams, did not use the word Tlatskani for the streams they would follow in order to get to that point, but the white men who settled here later did apply the name to the streams.
