Billboard number-one singles of 1945

This is a list of number-one songs in the United States during the year 1945 according to The Billboard. Prior to the creation of the Billboard Hot 100, Billboard published multiple singles charts each week. In 1945, the following three charts were produced:

• Best-Selling Retail Records – ranked the biggest selling singles in retail stores, as reported by merchants surveyed throughout the country.
• Records Most Played on the Air – ranked the most played songs on United States radio stations, as reported by radio disc jockeys and radio stations.
• Most Played Juke Box Records – ranked the most played songs in jukeboxes across the United States.

Beginning in March, a composite ten-position song chart called the Honor Roll of Hits combining data from the three aforementioned charts along with three other component charts was published.^[1] It served as the publication's lead chart until the introduction of the Billboard Hot 100 in 1958 and would remain in print until November 1963^]

Shown below is the list of #1 songs on the Honor Roll of Hits.
