Locust Hill was first settled about 1799 by Samuel Reynolds, a United Empire Loyalist from Dutchess County, New York.
The hamlet, centred on lots 10 and 11, concession 10.
Today the area is made up of existing and newer homes along Highway 7.

Locust Hill only became a place of significance with the arrival of the Ontario and Quebec Railway in the 1884, linking Toronto with Peterborough.
Area business leaders from Whitevale and Green River petitioned to create a railway station at Locust Hill.
The hamlet and station were named after the farm of William and Esther Reesor Armstrong, where locust trees were a prominent feature.

Locust Hill was one of the busiest stations on the Toronto-Perth line and was built on the St Clair Farm owned by Captain William Button on the northwestside of Highway 7.
Flour, brushes, livestock and milk were shipped out of Locust Hill in quantity.
In 1887 an elevator and mill were built east of the station, a water tower on the west side, and a co-operative creamery was built on the south side of Highway 7 on the east bank of the Rouge River in 1893 (it burned down in 1910).
The original Van Horne style one and half storey station burned down in 1935 and was replaced by a single floor station in 1936.
Rail service through Locust Hill ceased in 1969, but the line is still active.
The old Locust Hill Station has been relocated in 1983 and reconstructed at the Markham Museum and Historic Village and the station platform was removed and replaced with a grass strip.
