"La Rivière de notre enfance" is the name of a 2004 song recorded in duet by Canadian singer Garou and French singer Michel Sardou. It was released in November 2004 as the third single from Garou's second studio album, Reviens, as well as the first single from Sardou's 2004 album, Du Plaisir. The song was a No. 1 hit in France and Belgium (Wallonia) and also achieved success in Switzerland. It was the fourth No. 1 hit in France for Garou, making him the artist with the most weeks spent in that position up to that point.
As of August 2014, it is the 38th best-selling single of the 21st century in France, with 462,500 units sold.
It appears on a number of French compilations, including the charity album Solidarité Asie.
