Dennis Clifton Donaldson (June 9, 1938 – October 11, 2024) was an American politician from the state of Maryland. Born in Washington, D.C., he served in the U.S. Air Force from 1960 to 1966. He served as a Democratic member of the Maryland House of Delegates, representing Prince George's County-based district 26 from 1979 to 1983 and district 25 from 1983 to 1991, serving as speaker pro tempore for the final two years.

Donaldson considered a primary challenge against Congressman Roy Dyson in the 1990 cycle, receiving the endorsement of state house speaker R. Clayton Mitchell Jr., but declined to run, citing a lack of funds. He did not seek re-election that year, having accepted a position as a liaison between the Maryland Department of Transportation and the state legislature. He ran for a Maryland Senate seat on the lower Eastern Shore in 1994, losing to incumbent Republican J. Lowell Stoltzfus. He later worked as a political consultant, founding his own company, Donaldson Consultants. He died in Melbourne, Florida on October 11, 2024, at the age of 86.
