2010 Oregon State Treasurer special election

The 2010 Oregon State Treasurer special election was held on November 2, 2010, to elect the Oregon State Treasurer.

This election determined who would fill the remaining two years of the term of Ben Westlund, who died in office from lung cancer earlier in the year. Incumbent Democratic State Treasurer Ted Wheeler, who was appointed by Governor Ted Kulongoski to serve until this special election could be held, ran for election to the office. In primary elections held on May 18, Wheeler captured the Democratic nomination, and the Republicans picked State Senator Chris Telfer.

Wheeler won the election, defeating Telfer and two third-party candidates handily.
