Millersburg is a city in Linn County, Oregon, United States.

Millersburg came into being in 1974, to prevent the city of Albany from attempting to extend its city limits to include where Wah Chang Corporation operated a zirconium processing plant for the United States Bureau of Mines.

Although now owned by Allegheny Technologies and until recently known as ATI Wah Chang, this processing plant is the city's largest employer.

International Paper then closed the mill at the end of 2009, laying off 270 employees.
