District 3 of the Oregon State Senate comprises southern Jackson County.
It is currently represented by Democrat Jeff Golden of Ashland.
Therefore, senators before 2021 may not represent the same constituency as today.
From 1993 until 2003, the district covered parts of Washington and northern Multnomah counties; from 2003 until 2013, the district shifted to cover southern Jackson County; and from 2013 until 2023, the district boundaries only shifted slightly, covering more of Medford, adding the Applegate Valley, and losing Miller Mountain.
The current district is very similar to previous iterations, only losing significant area north of the Applegate River.
