2016 United States Senate election in Oregon

The 2016 United States Senate election in Oregon was held November 8, 2016, to elect a member of the United States Senate to represent the State of Oregon, concurrently with the 2016 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections.

Incumbent Democratic Senator Ron Wyden was re-elected to a fourth full term in office. This is the first senate election since 1998 in which Coos County has not supported him.
