District 7 of the Oregon State Senate comprises parts of northern Lane County in the Eugene metropolitan area. It is composed of Oregon House districts 13 and 14. It is currently represented by Democrat James Manning Jr. of Eugene.

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 southeast Portland; from 2003 until 2013, it covered most land in Lane County from north and west Eugene stretching north to Harrisburg and west to Cheshire; and from 2013 until 2023, it covered a similar area as previously detailed while losing some land from its southwest corner. The current district is similar to the previous iteration with the exception of the loss of Junction City and all previously included territory north of it while extending west to include Elmira and Veneta.

The results are as follows:^[1]
