Yapeyú is a town in the province of Corrientes, Argentina, in the San Martín Department.It is known throughout the country because it was the birthplace of General José de San Martín (1778–1850), hero of the War of Independence. One of its notable monuments is the Arco Trunco. The word Yapeyú comes from the Guaraní language and means "ripe fruit"; in other times, it was also the name of the river that is called today Guaviraví. Presbyter Eduardo J. Maldonado considers it a combination of the guaraní words "Yaye" ("The place where") and "Peyú" ("blowing of the wind"). Under this perspective, "Yapeyú" would mean in guaraní language "The place where the wind blows".
