James Pye (1801 – 30 December 1884) was an Australian orchardist and politician.
After an elementary education he joined his father's business and eventually had large orchards in the Field of Mars and Seven Hills district.
Pye was the patron of numerous organisations in the Parramatta region including the National School Board.
In the 1850s, Pye offered the land surrounding Hunts Creek at nominal cost to the Government to enable the construction of dam and reservoir, known as Lake Parramatta, that operated as a permanent water supply to the City of Parramatta between 1856 and 1909.
[1] In 1856, Pye was elected as one of the two members for Cumberland (North Riding) in the first New South Wales Legislative Assembly under responsible government.
