Mauckport is a town in Heth Township, Harrison County, Indiana, United States, along the Ohio River.

The Mauckport area's earliest permanent settlers came from the Shenandoah Valley and Lancaster County, Pennsylvania.

It was John Peter Mauck who started the state's first ferry, a raft and tow line crossing from Mauckport to Brandenburg, Kentucky on the opposite side of the river.

[5] In the earliest days, packetboats hauled timber and farm products from the port to other stops along the river.

Very early after the development of the steam ship, the town had a wharf and was a frequent stop for steam ships and river barges, as it being the closest river port to the original state capital of Corydon.

In 1847, the citizens of the town filed a petition to change the name of Mauckport to New Market.

Mauckport was the site of a small skirmish in July 1863 during "Morgan's Raid" in the American Civil War.

Mauckport was where Morgan and his men, aided by the citizens of neighboring Brandenburg, Kentucky, crossed the Ohio River to start his raid in earnest.

When Morgan returned fire with his own artillery the home guard quickly retreated back toward Corydon, leaving Mauckport undefended.

Upon landing his army on the east side of Mauckport, Morgan burnt the steam boat Alice Dean.

The citizens of Mauckport, having plenty of forewarning, abandoned the town and fled to the west until Morgan's army passed.

[6] In 1900, the Ohio River froze solid during the winter, destroying the town's ships.

Other factors contributing to the decline of the town's population included the rise of the railroad, which led to less reliance on the river for transportation.

The town still celebrates "Mauckport Days" every spring with a parade, and weekend of activities, bazaar style booths, and competitions.
