"Star Trek" fans are often particularly fond of Riverside, Iowa because it claims to be the fictional birthplace of Captain James T. Kirk, captain of the starship Enterprise on the original "Star Trek" television series. This character detail was introduced after the show had already been on the air, but it has been prominently discussed in several "Star Trek" novels.
While the creator of "Star Trek" has acknowledged that Captain Kirk was born and raised in Iowa, he did not specifically name Riverside as the character's hometown. However, the town of Riverside openly embraces this fictional identity, and there are a few different public monuments dedicated to Captain Kirk and "Star Trek." These objects include a sign declaring Riverside to be the "future birthplace" of Captain James Kirk.
