The Tanarello is a small river (stream) in Italy that gives rise to—alongside the Negrone—the Tanaro river in Liguria. Rising from springs located on the northern slope of Monte Saccarello in the Ligurian Alps in Piedmont, the Tanarello flows a northerly course into Linguria, before joining the Negrone at Pian Laiardo—between the municipalities of Cosio d'Arroscia and Ormea—to form the Tanaro.{{cite web|url=http://provincia.imperia.it/Portals/_provincia/Documents/BACINO%20DEL%20TANARO.pdf|title=Bacino del Tanaro|trans-title=Basin of the Tanaro|publisher=Province of Imperia|language=Italian|url-status=dead|archive-url=https://web.archive.org/web/20150329093507/http://provincia.imperia.it/Portals/_provincia/Documents/BACINO%20DEL%20TANARO.pdf|archive-date=29 March 2015|access-date=5 September 2022}}
