Diane Linthicum

Diane Linthicum is an American politician, currently serving on the Oregon State Senate. A member of the Republican Party, she represents the 28th district, which encompasses all of Klamath County as well as outlying parts of Deschutes and Jackson Counties.

She is the wife of the previous senator to hold this seat, Dennis Linthicum, who was deemed ineligible to run for re-election due to his participation in the 2023 Oregon Senate walkout and the passage of Measure 113, which denied eligibility to run for re-election to any state legislator with 10 or more unexcused absences in a legislative session.
