The first inauguration of Lyndon B. Johnson as the 36th President of the United States was held on Friday, November 22, 1963 aboard Air Force One at Love Field, following the assassination of President John F. Kennedy earlier that day. The inauguration marked the commencement of the first term (a partial term of 1 year, 59 days) of Lyndon B. Johnson as President. This was the eighth non-scheduled, extraordinary inauguration to take place since the presidency was established in 1789.

President Johnson chose federal district Judge Sarah T. Hughes, a long standing friend, to swear him in. He had previously sought her appointment to a federal judgeship, which Robert Kennedy initially rejected on advice from the Justice Department on account of her age (then 65 years old). When the Justice Department reversed its decision a few weeks later and appointed Hughes, Johnson was outraged at having not been consulted.

The swearing-in ceremony administered by Judge Hughes in an Air Force One conference room represented the first time that a woman administered the presidential oath of office as well as the only time it was conducted on an airplane. Instead of the usual Bible, Johnson was sworn in upon a missal found on a side table in Kennedy's Air Force One bedroom. After the oath had been taken, Johnson kissed his wife on the forehead. Mrs. Johnson then took Jackie Kennedy's hand and told her, "The whole nation mourns your husband."
