Olla is a town in La Salle Parish, Louisiana, United States. The population was 1,417 at the 2000 census.
In 1893 the Houston, Central, Arkansas, and Northern Railroad came through the area and helped add permanence to the town. It was incorporated as the town of Olla in August of 1899.
Olla is also known as the site of the only railroad holdup in the state of Louisiana. The robbers' goal was a large money shipment which was transferred before it reached the robbery site.
