District 22 of the Oregon State Senate comprises parts of north and northeast Portland. The district is composed of Oregon House districts 43 and 44. It is currently represented by Democrat Lew Frederick of Portland.

Election results District boundaries have changed over time. Therefore, senators before 2021 may not represent the same constituency as today. From 1993 until 2003, the district covered parts of Lane and Douglas counties; from 2003 until 2013, it shifted to cover north and northeast Portland; and from 2013 until 2023, it remained mostly unchanged, losing area in Sullivan's Gulch while gaining land bounded by NE 148th Avenue and railroad tracks running along NE Killingsworth St and NE Sandy Avenue.

The current district undoes those gains and losses from the previous iteration while simultaneously adding much of the Alameda and Cully neighborhoods and losing the Sumner neighborhood.
