Oregon's 26th Senate district

District 26 of the Oregon State Senate comprises all of Hood River County, as well as parts of Clackamas, Multnomah, and Wasco counties.

It is currently represented by Republican Daniel Bonham of Hood River.

From 1993 until 2003, the district covered parts of Southern Oregon; from 2003 until 2013, it shifted to cover all of Hood River County and eastern portions of Clackamas and Multnomah counties, including a panhandle in Clackamas; and from 2013 until 2023, it shifted east, losing most of southeastern Clackamas County and its previous panhandle but gaining a panhandle covering Happy Valley and outer southeast Portland surrounding Powell Butte.

The current district is similar to its previous iterations.

It has added the communities of Beavercreek, Canby, and Estacada in Clackamas County and Chenoweth, Mosier, and The Dalles in Wasco County.
