Robert Lee "Bob" DeProspero (December 31, 1938 – March 4, 2019) was an American law enforcement professional best known for his work in the United States Secret Service. Born in Morgantown, West Virginia, DeProspero served with the Secret Service from the mid-1960s through the 1980s and rose to direct the Presidential Protective Division following changes prompted by the 1981 shooting of President Ronald Reagan.

That division is the branch of the Secret Service charged with the personal protection of the president and immediate family, advance planning for movements, and coordination with other agencies.
