This is a list of number-one singles in the United States during the 1930s according to music historian Joel Whitburn.

Before the 1930s, only sporadic popular music charts appeared. In 1935, Your Hit Parade began publishing music charts, which were the first regular and consistently updated in the American music industry. Although Billboard magazine had featured charts before, in 1940, the trade paper began publishing them regularly, overtaking Your Hit Parade with its methodology and scope. Chart data is pulled from music historian Joel Whitburn, who, in addition to using Your Hit Parade and Billboard, has used historical sources such as press releases, news stories, and sales data to best represent what prospective charts would've looked like had they been regularly published.
