Seneca is a city in Grant County, Oregon, United States. It is located in the Blue Mountains about {{convert|23|mi|km}} south of Canyon City, on U.S. Route 395, on the edge of the Malheur National Forest.{{cite book |title= Oregon Atlas & Gazetteer |edition= 7th |year= 2008 |publisher= DeLorme |location= Yarmouth, Maine |isbn= 978-0-89933-347-2 |page= 78}} The population was 199 at the 2010 census.

History

File:2017-07-13 Seneca 03.jpg

Seneca post office was established in 1895 and named by postmaster Minnie Southworth for her brother-in-law, prominent Portland judge Seneca Smith.{{Cite OGN|7th|page=860}}

While early homesteaders moved into the valley in the late 1800s, Seneca only began growing in the 1929 when it became the northern terminus of the now-vacated Oregon and Northwestern Railroad, owned by the Edward Hines Lumber Company, which extended south to Burns.{{cite book |last= Engeman |first= Richard H. |title= The Oregon Companion: An Historical Gazetteer of The Useful, The Curious, and The Arcane |year= 2009 |publisher= Timber Press |location= Portland, Oregon |isbn= 978-0-88192-899-0 |pages= 337–338}} At that time, large-scale shipping of Ponderosa Pine logs from Seneca and the surrounding national forest began to the Hines sawmill in Hines. The company established a planing mill and railroad shops in Seneca, and it became essentially a company town. In 1940 Seneca's population was 275.{{cite book |url= https://archive.org/details/oregonendoftrail00writrich |title= Oregon: End of the Trail |author= Writers' Program of the Work Projects Administration in the State of Oregon |series= American Guide Series |year= 1940 |publisher= Binfords & Mort |location= Portland, Oregon |pages= [https://archive.org/details/oregonendoftrail00writrich/page/421 421]–422|oclc= 4874569}} Logging in the area began to decline in the 1970s, and the Hines company ceased operations of its lumber mills and railroad in 1984. The town was incorporated as a city in 1970 as lumber company control began to wane. According to the 1980 census, Seneca's population was 285. The estimated population in 2007 was 270.
