Oregon's 21st Senate district
District 21 of the Oregon State Senate comprises parts of Clackamas and Multnomah counties, including parts of southeast Portland, as well as Milwaukie and Oak Grove. It is currently represented by Democrat Kathleen Taylor of Portland.

Election results
District boundaries have changed over time, therefore, senators before 2013 may not represent the same constituency as today. From 1993 until 2003, the district covered parts of the Eugene metropolitan area, and from 2003 until 2013 it covered a slightly different area in the southern Portland metropolitan area.
