Richard Toll is a town in northern Senegal, lying on the south bank of the River Senegal, just east of Rosso. Originally a colonial town, it was named for the park of the Chateau de Baron Roger, laid out by botanist Jean Michel Claude Richard. A rice growing scheme was originally initiated by France's colonial development organisation, FIDES, in 1949 with an initial cultivated area of 6,000 hectares (14,830 acres). The town's main industry is sugar.
