Uruguayan Portuguese (, ), also known as () and Riverense, and referred to by its speakers as (), is a variety of Portuguese with heavy influence from Rioplatense Spanish. It is spoken in north-eastern Uruguay, near the Brazilian border, mainly in the region of the twin cities of Rivera (Uruguay) and Santana do Livramento (Brazil). This section of the frontier is called "Frontera de la Paz" (Border of Peace), because there is no legal obstacle to crossing the border between the two countries.
