The 1904 New South Wales state election was held on 6 August 1904. It involved 90 electoral districts returning one member each, a reduction from 125 to 90. Women were given the right to vote for the first time in New South Wales elections, almost doubling the number of enrolled voters. As a result, it is not possible to tell the notional holder of a seat prior to the election.
Orange Liberal MLA Harry Newman died on 1 June. Deniliquin Independent MLA Joseph Evans died on 5 July. Due to the proximity of the election, no by-elections were held.
Sitting members are shown in bold text. Successful candidates are highlighted in the relevant colour.
