The Army–McCarthy hearings were a series of hearings held by the United States Senate's Subcommittee on Investigations between April 1954 and June 1954. The hearings were held for the purpose of investigating conflicting accusations between the United States Army and Senator Joseph McCarthy. The Army accused chief committee counsel Roy Cohn of pressuring the Army to give preferential treatment to G. David Schine, a former McCarthy aide and a friend of Cohn's. McCarthy counter-charged that this accusation was made in bad faith and in retaliation for his recent aggressive investigations of suspected Communists and security risks in the Army.

Chaired by Senator Karl Mundt, the hearings convened on March 16, 1954, and received considerable press attention, including gavel-to-gavel live television coverage on ABC and DuMont from April 22 to June 17. The media coverage, particularly television, greatly contributed to McCarthy's decline in popularity and his eventual censure by the Senate the following December.
