Madisonville was founded by Jean Baptiste Baham in 1800 as the town of Cocquille or Cokie because of the abundance of shells in the area, at the site of the Native American village of Chiconcte. In 1810 it was renamed in honor of President of the United States James Madison.
Madisonville was an important port providing bricks and other products of the towns along the Tchefuncte to New Orleans in the decades before the Civil War. After the Union capture of New Orleans, this area remained under nominal Confederate control, and the cutoff of trade with New Orleans across "enemy lines" was devastating to the local economy, which did not recover for decades after the peace.
Much of the town flooded with the Lake Pontchartrain storm surge of Hurricane Katrina in 2005. The police station was destroyed by the floodwaters, along with the lower levels of the fire station. A temporary police substation was built by a Madisonville-based company, T. Sturdevant Inc/dba Barnstormers. The ruined police station was repaired by town workers and reopened for use, while the substation was left intact and is still used as the main office of the current Chief of Police, David Smith.
