Flinton Ontario is a hamlet in Lennox and Addington County in Eastern Ontario, Canada. The population is about 500, and it was founded by Billa Flint. The community is on the Skootamatta River whose falls were used to power many mills.

The village was built to house Billa Flint's employees, working at his mill on the river, which powered the entire community. Ruins of the mill can be seen at the Flinton Falls waterfall at the Flinton Conservation Area

The Skootamatta cascades over the dam and takes a sharp left south and rushes under the bridge. This is a very popular spot for kayakers!

Also found in the Flinton Conservation Area, are the remains of a dam and powerhouse that once provided early hydro-electric power to the community and to the nearby mines.

Built in the early 1900's, the dam on the Skootamatta River at Flinton Falls was built out of concrete. The water was channeled through two spillways where the force was used to turn two turbines, which can still be seen. Much of the structure remains intact and is very photogenic most times of the year.
