Lacassine (French: La Cassine) is an unincorporated community in Jefferson Davis Parish in the U.S. state of Louisiana. The Little Kahuna Water Park was being constructed off Interstate 10 in Lacassine, but was never completed due to monetary problems. Lacassine is home of the Louisiana Spirits Distillery, where Bayou Rum, a popular adult beverage in Louisiana, is distilled. Construction began in 2011 and Bayou Rum was created in 2013.
One story about the name of the community is that a tribe of Comanche Indians, led by their chief Lacassine, migrated to southwest Louisiana to hunt and fish in the early 19th century, settling near this place.
Another story about the name states that the part of the parish where the community is located was visited regularly by different tribes of the area, including Attakapas and Choctaw. Game was abundant here, and the Indians called it their "hunting ground," or, in the Choctaw language, La Cassine. However, the phrase sounds more French than Indian. La Cassine means "the small house" in French. According to Monsignor Jules Daigle, noted authority of the Cajun language, it was named for a small house built by an Indian chief in that location.
