Clifford is an unincorporated community in the municipality of Minto in Wellington County in Southwestern Ontario, Canada. It is on Ontario Highway 9 and Coon Creek, a stream in the Saugeen River drainage basin. The village of Clifford was founded around 1855 as Minto Village. After the opening of the post office in 1856, the settlement was renamed Clifford by the first postmaster Francis Brown after Clifford in West Yorkshire, England. Clifford was incorporated as a village in 1873. In 1999, Clifford was amalgamated with Palmerston, Harriston and Minto Township to create Minto.
