The Cass County Dentzel Carousel, formerly known as the Spencer Park Dentzel Carousel and also known as the Riverside Park Dentzel Carousel or Logansport Carousel, is a historic carousel in Riverside Park of Logansport, Indiana. Built by the Dentzel Carousel Company, probably by 1900, it is one of the company's oldest surviving menagerie-style carousels, with animals likely hand-carved by George Dentzel. It was declared a National Historic Landmark in 1987.
