John Perry (1849 – 2 January 1935) was an Australian politician.
A founding member of the Farmers' and Settlers' Association of New South Wales, he was also closely involved in the Australian Shearers' Union.
An early member of the Labor Party, he ran for the New South Wales Legislative Assembly as the endorsed Labor candidate for Quirindi in 1895 and 1898, but by his successful election in 1904 as the member for Liverpool Plains he was describing himself as an Independent Liberal.
Defeated as an endorsed Liberal in 1907, he was returned to the parliament in sensational circumstances in August 1911, when he won the by-election for his old seat caused by the resignation of his successor, Henry Horne, over land policy.
His four-vote victory was overturned on appeal and he lost the subsequent by-election in October.
