Joseph John Holmes (24 May 1866 – 25 April 1942) was an Australian politician who served in both houses of the Parliament of Western Australia.

The firm, Holmes Brothers, later expanded to Perth and to the Eastern Goldfields (during the gold rushes of the 1890s), generating large profits.

[1] At the 1897 general election, Holmes won the newly created seat of East Fremantle, defeating Matthew Moss by just six votes.

[2] However, that result was overturned by the Supreme Court of Western Australia in April 1906, due to issues of voter fraud.

[6] Holmes re-entered parliament in 1914, winning a Legislative Council by-election for North Province (caused by the death of Richard Pennefather).
