This is a list of members of the Australian Senate from 1904 to 1906. Half of its members were elected at the 29–30 March 1901 election and had terms deemed to start on 1 January 1901 and finishing on 31 December 1906; the other half were elected at the 16 December 1903 election and had terms starting on 1 January 1904 and finishing on 30 June 1910, extended as a result of the 1906 referendum, which changed Senate terms to finish on 30 June, rather than 31 December.
