Let Us Continue is a speech that 36th President of the United States Lyndon B. Johnson delivered to a joint session of Congress on November 27, 1963, five days after the assassination of his predecessor John F. Kennedy. The almost 25-minute speech is considered one of the most important in his political career.

After Kennedy's assassination, Johnson, until then Vice President, ascended to the position. To publicly emphasize stability by the continuity of government, Johnson made efforts to persuade key people from the Kennedy administration to stay in office. Subsequently, various Kennedy officials, including his brother and Attorney General Robert F. Kennedy, stayed in the Cabinet. Former President Dwight D. Eisenhower had a conversation with Johnson in the Executive Office Building, and in a confidential memorandum, he suggested that Johnson call a joint session of the Congress and deliver a speech. Soon after, Johnson asked Ted Sorensen, Kennedy's chief speechwriter, to prepare a draft version for his speech. Input about the subject matter and content of the speech came from various advisers, including John Kenneth Galbraith.

It was decided to broadcast the speech on television on November 27. After at least nine draft versions, Johnson studied the final version that same morning, making a few minor changes. In his address, he called Kennedy the "greatest leader of our time", and said that "American dreams have been vitalized by his drive and by his dedication." He called for the earliest possible passage of the civil rights law, and demanded that Congress pass tax reform that would bring tax relief. In contrast with Kennedy's 1961 inauguration address' focus on a new beginning, Johnson said "Today, in this moment of new resolve, I would say to all my fellow Americans, let us continue." He closed the speech with a stanza from "America the Beautiful".

The speech was interrupted 34 times by applause from the audience. It was widely appreciated, and the New York Herald Tribune described his address as "fine words, fitting words, at times inspiring words". Soon after his address, Johnson succeeded in getting the tax reform bill and the Civil Rights Act passed by Congress.

On November 22, 1963, President John F. Kennedy was assassinated in Dallas, Texas, at about 12:30 p.m. CST. Upon his death, Vice President Lyndon B. Johnson succeeded to the presidency. Johnson took the oath of office aboard Air Force One. After the plane landed at Andrews Air Force Base near Washington, D.C., he gave a brief address to the public, which lasted less than 40 seconds. Kennedy's widow Jacqueline Kennedy, his brother Robert F. Kennedy, and his children remained at the center of media and public attention in the following days, particularly during the funeral ceremonies on November 25, 1963.

Johnson, who had fallen into political isolation with his vice-presidency, was systematically pushed aside by many of Kennedy's advisers. Following the assassination, immediately upon his arrival at his official vice-presidential residence at the Executive Office Building, Johnson spoke with Everett Dirksen, the Republican leader in the Senate, and with John W. McCormack, the Democratic speaker of the House of Representatives. In the following days, he held telephone calls and meetings with various union leaders and representatives of the civil rights movement including Martin Luther King Jr. and Whitney Young. Johnson also contacted the opinion leaders of political liberalism and conservatism in Congress. He asked for support and help in the task of leading the United States out of the crisis that had been caused by Kennedy's assassination. He also pursued this intention on November 25, 1963, when he met with state governors. To publicly emphasize stability by the continuity of government work, Johnson made efforts to persuade key people from the Kennedy administration to stay in office. Subsequently, prominent Kennedy advisers and cabinet members including Robert McNamara, Dean Rusk, McGeorge Bundy, Ted Sorensen, Pierre Salinger, and Adlai Stevenson II continued in their official positions. Even Robert F. Kennedy, who had been associated with Johnson in mutual dislike since their first meeting, was persuaded to continue his duties as the Attorney General.

All three presidents who were still living at the time pledged their support to Johnson. Former President Harry S. Truman advised him from his own experience of assuming the presidency upon his predecessor Franklin D. Roosevelt's death, while former President Dwight D. Eisenhower arrived in Washington, D.C., and had a conversation with Johnson in the Executive Office Building. In a confidential memorandum, Eisenhower suggested to Johnson to call a joint session of the Congress and deliver a speech of around 12 minutes. Concluding his memorandum, Eisenhower wrote: "You hope that people of government and the entire nation may now mobilize their hearts, their hands and their resources for one purpose—to increase the spiritual and material resources of the nation and to advance her prestige and her capacity for leadership in the world for peace."

Soon after, Johnson asked Ted Sorensen, Kennedy's chief speechwriter, to prepare a draft version for his speech. Initially, several cabinet members and White House staff suggested that Johnson address the nation from the Oval Office. However, after Eisenhower's memorandum, Johnson felt that the Capitol seemed suitable for the speech, as he had served long as a senator, and was often referred to as "Master of the Senate". On the afternoon of November 23, it was decided that Johnson would address the Congress on November 27. On November 25, Johnson attended Kennedy's state funeral, and met with various foreign dignitaries including Lester Pearson, the prime minister of Canada; Hayato Ikeda, the prime minister of Japan; Anastas Mikoyan, the deputy premier of the Soviet Union; Alec Douglas-Home, the prime minister of the United Kingdom; and Charles de Gaulle, the president of France. A day before the funeral, Lee Harvey Oswald, the man accused of killing President Kennedy was fatally shot by nightclub operator Jack Ruby. Johnson put together a team to develop speech drafts, which included Sorensen, John Kenneth Galbraith, McGeorge Bundy, Horace Busby, and Bill Moyers. Several other advisers provided essential ideas and thoughts for the planned speech; inputs came from Abe Fortas (a lawyer and friend of Johnson), Senator Hubert Humphrey, Senator Mike Mansfield, Dean Rusk, Douglas Dillon, Adlai Stevenson, Orville Freeman, and Kermit Gordon. Author Merle Miller wrote that "everybody knew it would be the most important speech of Johnson's career." Many Americans did not know Johnson, and he felt that it was necessary to establish a trust and sense of leadership. Johnson initially agreed to the draft version presented to him by Galbraith; however, on November 25, Sorensen vehemently opposed Galbraith's draft as it presented Johnson in a deprecatory way. Subsequently, Sorensen presented a draft that paid tribute to Kennedy and seemed like his personal obituary. In his versions of the draft, Johnson remained in the shadow of his predecessor and was presented as someone who would implement the ideas of his predecessor, but was unwilling to take on independent and hands-on leadership.
