A by-election was held for the Australian House of Representatives seat of Riverina on 18 May 1904. This was triggered after the result at the 1903 election, which had seen Free Trade candidate Robert Blackwood narrowly defeat Protectionist MP John Chanter, was declared void due to allegations of electoral irregularities.{{cite AustLII |litigants=Chanter v Blackwood (No 1) |link=Chanter v Blackwood |year=1904 |court=HCA |num=2 |parallelcite=[http://www.austlii.edu.au/au/cases/cth/HCA/1904/2.pdf (1904) 1 CLR 39]}} and {{cite AustLII |litigants=Chanter v Blackwood (No 2) |year=1904 |court=HCA |num=48 |parallelcite=[http://www.austlii.edu.au/au/cases/cth/HCA/1904/48.pdf (1904) 1 CLR 121]}}.
