Foy Property Provincial Park, Provincial park in Renfrew County, Canada

Foy Property Provincial Park sits on the northeast shore of Round Lake in Renfrew County. Mature forests of White Pine, Oak, and Eastern Hemlock grow across the park's granite bedrock.

The land was purchased in 1968 as an addition to Bonnechere Provincial Park, also on Round Lake. Heavy day use at Bonnechere in the early 1980s prompted the idea of a second park on the lake. In 1985 the property was put into regulation as Foy Provincial Park, classed as "recreation" with the stated goal of maintaining quality summer-oriented day-use facilities. Declining attendance led the Ministry of Natural Resources to close the day-use facilities in 1994.

For decades the Round Lake Ontario Ranger Program ran its camp at Foy, with portables on site until they were removed about a decade after the program was cancelled in 2012; an Indigenous yurt owned by the Algonquin First Nation now stands in their place. The park is non-operational, so camping is prohibited while day-use swimming and hiking are allowed.

Foy is a non-operational park: camping is prohibited, while swimming and hiking are allowed as day-use activities. Access is by walking in from Red Rock Road, where visitors park outside the gate; in August 2025 more than 50 vehicles could be counted along the road on an average summer weekend. The local council is reviewing a proposal for a parking lot inside the park, which some residents oppose.

The 1986 management plan set aside two nature reserve zones on the park's point: the west side protects a wave-cut terrace left by a glacial lake, while the east side protects exposed clay. The outflow dam in Grassy Bay is opened each year on September 7 to lower Round Lake's water levels.
