Spirit of Peoria is a riverboat that ran in the Peoria, Illinois area from 1988 to 2022. The boat participated in the 2004 Grand Excursion. Spirit of Peoria is a true paddleboat, actually using its paddlewheel for propulsion, unlike some modern riverboats with purely cosmetic wheels.

The Grand Excursion was a promotional voyage by train and steamboat into the Upper Mississippi River valley, USA that first took place in June 1854. It marked the first railroad connection between the East Coast and the Mississippi River, and it included dignitaries such as former president Millard Fillmore. In 2004, 150 years later, the Grand Excursion route was retraced by both riverboats and a steam locomotive.
