"Ich bin ein Berliner" (German pronunciation: [ bn an blin]; "I am a Berliner") is a speech by United States President John F. Kennedy given on June 26, 1963, in West Berlin. It is one of the best-known speeches of the Cold War and among the most famous anti-communist speeches.

Twenty-two months earlier, East Germany had erected the Berlin Wall to prevent mass emigration to West Berlin. The speech was aimed as much at the Soviet Union as it was at West Berliners. Another phrase in the speech was also spoken in German, "Lasst sie nach Berlin kommen" ("Let them come to Berlin"), addressed at those who claimed "we can work with the Communists", a remark at which Nikita Khrushchev scoffed only days later.

The speech is considered one of Kennedy's finest, delivered at the height of the Cold War and the New Frontier. It was a great morale boost for West Berliners, who lived in an enclave deep inside East Germany and feared a possible East German occupation.

Speaking to an audience of 120,000 on the steps of Rathaus Schneberg, Kennedy said,

Two thousand years ago, the proudest boast was civis romanus sum ["I am a Roman citizen"]. Today, in the world of freedom, the proudest boast is "Ich bin ein Berliner!"... All free men, wherever they may live, are citizens of Berlin, and therefore, as a free man, I take pride in the words "Ich bin ein Berliner!"

Kennedy used the phrase twice in his speech, including at the end, pronouncing the sentence with his Boston accent and reading from his note "ish bin ein Bearleener", which he had written out using English orthography to approximate the German pronunciation. He also used the classical Latin pronunciation of civis romanus sum, with the c pronounced [k] and the v as [w].

For decades, competing claims about the origins of the "Ich bin ein Berliner" overshadowed the history of the speech. In 2008, historian Andreas Daum provided a comprehensive explanation, based on archival sources and interviews with contemporaries and witnesses. He highlighted the authorship of Kennedy himself and his 1962 speech in New Orleans as a precedent, and demonstrated that by straying from the prepared script in Berlin, Kennedy created the climax of an emotionally charged political performance, which became a hallmark of the Cold War epoch.There is a widespread misconception that Kennedy accidentally said he was a Berliner, a German doughnut specialty. This is an urban legend which emerged several decades after the speech, and it is not true that residents of Berlin in 1963 would have mainly understood the word "Berliner" to refer to a jelly doughnut or that the audience laughed at Kennedy's use of this expression.

John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), often referred to by his initials JFK, was an American politician who served as the 35th president of the United States from 1961 until his assassination near the end of his third year in office. Kennedy served at the height of the Cold War, and the majority of his work as president concerned relations with the Soviet Union and Cuba. A Democrat, he represented Massachusetts in both houses of the U.S. Congress prior to his presidency.

Born into the prominent Kennedy family in Brookline, Massachusetts, Kennedy graduated from Harvard University in 1940 before joining the U.S. Naval Reserve the following year. During World War II, he commanded a series of PT boats in the Pacific theater. Kennedy's survival of the sinking of PT-109 and rescue of his fellow sailors made him a war hero for which he earned the Navy and Marine Corps Medal, but left him with serious injuries. After a brief stint in journalism, Kennedy represented a working-class Boston district in the U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate and served as the junior senator for Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage, which won a Pulitzer Prize. In the 1960 presidential election, he narrowly defeated Republican opponent Richard Nixon, who was the incumbent vice president. Kennedy's humor, charm, and youth in addition to his father's money and contacts were great assets in his campaign. Kennedy's campaign gained momentum after the first televised presidential debates in American history. He was the first Catholic elected president.

Kennedy's administration included high tensions with communist states in the Cold War. As a result, he increased the number of American military advisers in South Vietnam. The Strategic Hamlet Program began in Vietnam during his presidency. In April 1961, he authorized an attempt to overthrow the Cuban government of Fidel Castro in the failed Bay of Pigs Invasion. Kennedy authorized the Cuban Project in November 1961. He rejected Operation Northwoods (plans for false flag attacks to gain approval for a war against Cuba) in March 1962. However, his administration continued to plan for an invasion of Cuba in the summer of 1962. The following October, US spy planes discovered Soviet missile bases had been deployed in Cuba; the resulting period of tensions, termed the Cuban Missile Crisis, nearly resulted in the breakout of a global thermonuclear conflict. He also signed the first nuclear weapons treaty in October 1963. Kennedy presided over the establishment of the Peace Corps, Alliance for Progress with Latin America, and the continuation of the Apollo program with the goal of landing a man on the Moon before 1970. He also supported the civil rights movement, but was only somewhat successful in passing his New Frontier domestic policies.

On November 22, 1963, he was assassinated in Dallas. Vice President Lyndon B. Johnson assumed the presidency upon Kennedy's death. Marxist and former U.S. Marine Lee Harvey Oswald was arrested for the assassination, but he was shot and killed by Jack Ruby two days later. The FBI and the Warren Commission both concluded Oswald had acted alone. After Kennedy's death, Congress enacted many of his proposals, including the Civil Rights Act and the Revenue Act of 1964. Despite his truncated presidency, Kennedy ranks highly in polls of U.S. presidents with historians and the general public. His personal life has also been the focus of considerable sustained interest following public revelations in the 1970s of his chronic health ailments and extramarital affairs. Kennedy is the most recent U.S. president to have been assassinated as well as the most recent U.S. president to die in office.
