Mexico is a town in the northeastern section of Oswego County, New York, United States.

Mexico has been referred to as the "Mother of Towns", as the original town as enacted by separate acts of 1792 and 1796 comprised an area that would eventually form six separate counties (Onondaga, Cortland, Oneida, Lewis, Jefferson, and Oswego).

The original organization of the proposed Mexico County and a town of that name was abandoned for a time.

The presence of roads, log cabins, frame houses, and businesses encouraged growth.

Mexico's early businesses included saw mills, oil-mills, gristmills, asheries, tanneries, blacksmiths, tinsmiths, coopers, cheese plants, cloth-dressings, distilleries, shoe-shops, hotels, general merchandise, and jewelers.
