This is a list of all senators who have served in the Nebraska Legislature since it became a unicameral body in 1937. Records show that the apportionment of the legislative districts established for the 1936 election remained unchanged through the election of 1962. The boundaries of these districts were restricted to fall along county lines. In the election of 1962, the voters of Nebraska passed a measure to loosen the county-line boundary restriction and to increase the number of legislative districts from 43 to 49. This resulted in a new apportionment that renumbered all the existing districts and added two additional districts to Lancaster County, three additional districts to Douglas County, and one north of Douglas county. That plan went into effect for the election of 1964.
