Donald R. Knabe (/kˈnɑːbiː/) (born October 15, 1943, in Illinois) is a former member of the Los Angeles County Board of Supervisors, serving the Fourth District.

The long east–west district runs from Marina del Rey and LAX through the South Bay, Los Angeles Harbor Region, and the Gateway Cities, to the southeastern San Gabriel Valley.

Grisham lost the special election to Democratic Norwalk City Councilman Cecil Green by a larger-than expected margin, and Republicans immediately concluded that the younger, more energetic Knabe should have been the nominee.

[1] Don Knabe, who had served as Dana's chief deputy since 1982, ran to fill the vacated seat.

[5] In the general election, he defeated former Rolling Hills Mayor Gordana Swanson, who had given Dana a tough race in 1992.

[7][8] Despite the family ties, Knabe routinely voted on board matters involving clients that his son and the latter's firm represented (including the award of government contracts), instead of recusing himself.

[9] Because of the father-son relationship, local media, in particular the Los Angeles Times, regularly raised ethical concerns over perceived or real conflicts of interest.
