The following lists the number one singles on the Australian Singles Chart during the 1940s.

The source for this decade is the "Kent Music Report". These charts were calculated in the 1990s in retrospect, by David Kent, using archival data. Before 1949, charts in Australia were only available on a monthly basis.

Note: during the 1940s, often more than one version of a particular song by different artists charted at the same time, thus more than one artist may be listed for a song. Different versions are separated by a semi-colon (;).
