John Louis Treflé (4 December 1865 – 11 January 1915) was a farmer, newspaper proprietor and politician in New South Wales, Australia.
The family moved to Temora, New South Wales around 1876, and Treflé was a boarder at St Patrick's College, Goulburn.
Treflé attempted unsuccessfully to forge links between the Farmers and Settlers Association and Labour, particularly in relation to agricultural policy and plans for a national bank.
[1] In 1904 he was a candidate at the election for The Upper Hunter, with the support of the Farmers' and Settlers' Association, but was unsuccessful with a margin of 955 votes (21.0%).
George Beeby, the Secretary for Lands, resigned from the ministry, parliament and party in protest at the power of the extra-parliamentary Labor Party executive in December 1912 and Treflé took on the additional portfolio of Lands.
