Shamrock Lakes is a town in Licking Township, Blackford County, Indiana, United States. As of the 2020 census, Shamrock Lakes had a population of 222. It was incorporated on May 21, 1973—and was the first community in Indiana to do so in 50 years. The small town consists of a group of six lakes that were created between 1960 and 1965, and the first lake was originally intended to be a water supply for a farmer's cattle. The community was listed on the front page of USA Today as one of only five places in the United States named after Ireland's clover emblem, the shamrock.
