The '''Toce''' ({{IPA|it|ˈtoːtʃe, ˈtɔːtʃe}}; {{langx|lmo|Toss}}; {{langx|wae|Riiss}}) is a river in [[Piedmont]], [[Italy]], which stretches the length of the [[Val d'Ossola]] from the [[Switzerland|Swiss]] border to [[Lake Maggiore]] into which it debouches near [[Fondotoce]] in the [[Comune|commune]] of [[Verbania]]. The river is {{convert|83.6|km|mi}} long<ref name="PTA_al5" /> and is formed in the upper [[Val Formazza]] by the confluence of a number of torrents in the plain of Riale.

== Geography ==
[[Image:CascataDelToceAug122024 02.jpg|thumb|left|The waterfall near [[La Frua]]]]
The source of one of these, the Gries, is situated on the Italian southern side of the [[Gries Pass]]; another forms beneath the [[Passo di San Giacomo]], others flow from little [[Alpine region|Alpine]] lakes such as Lago Castel and Lago di Sabbione.

South of [[La Frua]] the water of the river plummets {{convert|143|m|ft}} over the [[Cascata del Toce]] into the [[Formazza Valley]], through which it flows before transversing [[Valle Antigorio]] after another series of cascades. Near [[Crevola d'Ossola]] the river [[Diveria]] flows into the Toce. At this point, the valley gets wider and is known as [[Val d'Ossola]]. The Toce flows next to the capital of the valley, [[Domodossola]], and then [[Villadossola]] and [[Ornavasso]]. After a total of {{convert|76|km|mi}} the Toce then flows into Lake Maggiore.
The major tributaries are the [[Diveria]], [[Bogna (river)|Bogna]], [[Melezzo Occidentale]] (joining it near [[Domodossola]]), [[Ovesca]], [[Anza (river)|Anza]] (near [[Piedimulera]]), and the [[Strona]] (near [[Gravellona Toce]]).

== History ==
In ancient times the Toce river was called ''Athisone'' or ''Atisone'', whence the current name is derived. Old alternative forms in Italian include ''Toccia'' and ''Tosa''.
