Krotz Springs is a town in St. Landry Parish, Louisiana, United States, on the Atchafalaya River. The population was 1,198 at the 2010 census, down from 1,219 in 2000. It is part of the Opelousas–Eunice Micropolitan Statistical Area.

Around the turn of the 20th century, an Ohio native, Charles William Krotz, bought 20,000 acres (81 km) of woodland around the Atchafalaya Basin and set up a sawmill to trim the trees hauled out of the basin. The tiny settlement that grew up around the mill was called Latania (fan palm), after the bayou of the same name and the types of palm plants found in the area.

Thinking he was sitting on an untapped pool of oil, Krotz attempted to drill the first oil well in St. Landry Parish in 1900, but he struck water instead of oil, the result becoming known as Krotz’s spring. The spring was used to supply water for the developing sawmill town, and Krotz even bottled the water, selling it throughout the country.

In 1909, a post office was established in the town, and the obvious choice of a name was Krotz Springs.

The Krotz Springs Bridge spanning the Atchafalaya River opened in 1928 and carried railroad and automobile traffic. It was superseded by other bridges at the same location in 1934, 1973, and 1988.

Robert A. Moran, a Democrat served as mayor from 1986 until his death in May 1987. On November 21, 1987, James Rasie Nall defeated Ina Moran (D) in a runoff election for mayor. Four years later, on October 6, 1990, Gary Soileau (D) defeated Larry Martinez, Sr. (D), in a landslide victory with 86 percent of the ballots cast. Soileau would remain mayor until he retired in 2010, when he was succeeded by current mayor Carroll Snyder, another Krotz Springs Democrat.
