List of Billboard number-one dance singles of 1974 and 1975

Billboard began compiling the top-performing dance singles in the United States with the Disco Action chart in 1974. Premiered on the issue dated October 26, the chart ranked the popularity of songs in New York City discothèques, expanded to feature multiple charts each week which highlighted playlists in various cities such as San Francisco, Los Angeles, Miami, Chicago, Boston, Phoenix, Detroit and Houston. During this time, Billboard rival publication Record World was the first to compile a dance chart which incorporated club play on a national level. Noted Billboard statistician Joel Whitburn has since "adopted" Record World chart data from the weeks between March 29, 1975, and August 21, 1976, into Billboards club play history. For the sake of continuity, Record World national charts are incorporated into the 1975 and 1976 lists.^[1] With the issue dated August 28, 1976, Billboard premièred its own national chart ("National Disco Action Top 30") and their data is used from this date forward.^[1]

"Never Can Say Goodbye" (1974) by Gloria Gaynor is the first ever dance number-one single reported by Billboard.
