The town's first settler, Green Bently, purchased and developed farmland on the site of the village in 1798. The community was once known as "Millvale" after the village was laid out in 1825. The name was changed to "Millport" in 1829 to recognize its new status by the Chemung Canal which passed by the village. The presence of the canal helped raise the population about 1,000 for a time. Catharine Creek, a north-flowing tributary of Seneca Lake, flows through the village.
In the 1840s, several epidemics reduced the population of Millport.
