Randolph Collier (July 26, 1902 – August 2, 1983) was a member of the California State Senate.

[2][3] Collier served as chairman of the California Senate Transportation Committee and was the sponsor and co-author of the Collier–Burns Highway Act of 1947, which laid the groundwork for the California Freeway and Expressway System.

He was chairman of the Senate Interim Committee on Highways, Streets and Bridges.

[4] A rest stop in Siskiyou County, where he lived nearly all of his life, is named after him,[5] as is a tunnel on the Redwood Highway, U.S. Route 199.

In 1976, Collier was defeated for re-election by former state Assemblyman Ray E. Johnson and moved to Sacramento, where he spent the remainder of his life until dying of chronic pulmonary obstruction at the age of 81.
