Pittsford is an unincorporated community and census-designated place (CDP) located in Hillsdale County, Michigan.

As an unincorporated community, Pittsford lacks legal autonomy but does have its own post office, which serves the 49271 ZIP Code.

Although the post office was temporarily closed from September 12 to December 3, 1845, it was later relocated to the western part of Pittsford Township and renamed Sparta on January 4, 1846.

In turn, the nearby Keene post office was transferred and renamed Pittsford on January 30, 1846.
