As early as 1807, the community that later became Napoleonville was known as Canal, a name derived from a man-made waterway that extended west from the settlement to Lake Verret. This canal served as an important transportation link for goods and people in the early 19th century.
The village was later named Napoleonville by a former French soldier, Pierre Charlet, who had served under Napoleon Bonaparte. Charlet immigrated to Louisiana after the Napoleonic Wars and settled in Assumption Parish; he is buried in the cemetery of Our Lady of the Assumption Catholic Church in nearby Plattenville.
