The Lot, pronounced: [lɔt], originally the Olt (Occitan: Òlt; Latin: Oltis), is a river in France, right tributary of the Garonne. It rises in the Cévennes, flowing west through Quercy, where it flows into the Garonne near Aiguillon, a total distance of 481 kilometres (299 mi). It gives its name to the Lot département.
The Lot is prone to flooding in the winter and spring.

The river was used for transport as early as the 12th century when 11 flash locks were installed between Penne-d'Agenais and Fumel. A reliable route was not provided until the 17th century when Jean-Baptiste Colbert ordered new works. By 1776, the river had 12 locks. New construction was begun in 1835 for some 297 kilometres (185 mi) and 76 locks, connecting Le Moulin d'Olt at Entraygues to the Garonne at Nicole. Four tunnels were included at this time with lengths from 139 to 364 metres (456 to 1,194 ft). Railway competition caused the abandonment of Lot navigation in 1926. Over the next 60 years, there were no repairs or maintenance of the canal. Repairs in the Lower Lot began in the end of the 1990s.
