Alexander Stewart Provincial Park is a nature reserve in McNab/Braeside, Renfrew County, Ontario, Canada, about 11 kilometres (7 mi) west of the centre of Arnprior.

[2] This nature reserve contains a hardwood forest of several species including maple, American beech, basswood, blue-beech, and bur oak.

The subsurface is clay silt, a remnant of the ice age Champlain Sea.

The property was bought in 1860 by the eponymous Alexander Stewart, and donated by his children to the province in 1966.
