John Fitzgerald Kennedy (29 May 1917 - 22 November 1963) was the 35th president of the United States, serving from 20 January 1961 until his assassination on 22 November 1963. A Democrat from Massachusetts, he served in the U.S. House of Representatives (1947-1953) and Senate (1953-1961) before his presidency, and was the youngest person elected to the office and the first Roman Catholic president. His presidency coincided with a tense phase of the Cold War, and his death in Dallas, Texas, remains a subject of ongoing dispute regarding the number and identity of those responsible; see john-f-kennedy-assassination-viewpoint-debate and john-f-kennedy-history.

Kennedy's term was dominated by Cold War crises and the early Civil Rights Movement. His administration saw a failed attempt to overthrow the government of Fidel Castro at the Bay of Pigs in April 1961, and in October 1962 the discovery of Soviet ballistic missiles in Cuba touched off the Cuban Missile Crisis, which carried a risk of nuclear war before ending in a negotiated withdrawal. In June 1961 Kennedy met Soviet premier Nikita Khrushchev in Vienna, where the two failed to resolve the status of Berlin, and construction of the Berlin Wall followed weeks later. Kennedy also increased U.S. military advisers in South Vietnam and authorized the Strategic Hamlet Program, expanding American involvement in the region. Domestically, the economy expanded at an average annual rate of 5.5 percent from early 1961 to late 1963, with unemployment falling from nearly 7 percent to 5.5 percent. Kennedy proposed civil rights legislation and federal action on poverty that were largely enacted after his death. He also set the goal of a crewed Moon landing and launched the Peace Corps and Alliance for Progress. Historians and the public continue to debate the comparative weight of his foreign-policy record, his civil-rights legacy, and his personal conduct; see john-f-kennedy-legacy-viewpoint-debate.

• Transformative-leader viewpoint - holds that Kennedy's handling of the Cuban Missile Crisis, his rhetorical leadership, and his initiatives on civil rights, space exploration, and foreign aid mark him as one of the most consequential and admired modern presidents. See john-f-kennedy-transformative-leader-viewpoint.
• Image-over-substance viewpoint - holds that Kennedy's reputation rests disproportionately on style, youth, and martyrdom following his assassination, and that his legislative record and foreign-policy judgment (including Vietnam escalation and the Bay of Pigs) were modest or flawed. See john-f-kennedy-image-over-substance-viewpoint.
• Civil-rights-cautious viewpoint - holds that Kennedy was a reluctant and politically calculating actor on civil rights who acted mainly under public pressure rather than from sustained personal commitment. See john-f-kennedy-civil-rights-cautious-viewpoint.
• Cold War hawk viewpoint - holds that Kennedy's firmness toward the Soviet Union and Cuba, including covert action against Castro, was a necessary and effective defense of U.S. interests. See john-f-kennedy-cold-war-hawk-viewpoint.
• Vietnam-escalation-critical viewpoint - holds that Kennedy's decisions on military advisers and the Strategic Hamlet Program set the trajectory toward deeper U.S. involvement in Vietnam, regardless of his private intentions regarding later withdrawal. See john-f-kennedy-vietnam-escalation-critical-viewpoint.

• The assassination of John F. Kennedy and its investigation remain disputed regarding whether Lee Harvey Oswald acted alone or as part of a broader conspiracy. See assassination-of-john-f-kennedy-lone-gunman-controversy.
• Kennedy's extramarital relationships while in office, and the extent to which contemporary press and associates concealed them, are a matter of historical dispute. See john-f-kennedy-personal-conduct-controversy.
• The degree to which Kennedy's administration authorized or tolerated covert operations against Fidel Castro, including assassination plots, is contested based on later congressional findings. See john-f-kennedy-castro-covert-action-controversy.
