Settlers began arriving around 1797. Originally known as "King's Settlement", then Bucksville, finally, the name was changed to Port Byron in 1825 as it became a port on the Erie Canal. It has been suggested that the new name may have been chosen in reference to Lord Byron, the English romantic poet who had died the previous year, however there is no definitive proof of this. Later, when the canal route was changed in 1856, the village was a railroad town. The village was incorporated in 1837.
