Alto Paraná (Spanish pronunciation: [ˈalto paɾaˈna]; Upper Paraná) is a department in Paraguay. The capital is Ciudad del Este (formerly known as Puerto Presidente Stroessner, originally Puerto Flor de Lis).

The Alto Paraná department has experienced tremendous economic and population growth in the past 50 years. Most of this growth has been concentrated in the department capital of Ciudad del Este, and mainly occurred after the construction of the Puente de la Amistad bridge in 1961, which connects Paraguay and Brazil. This department is home to the Itaipu power plant, which supplies 95% of the energy consumed by Paraguay, and the Acaray Dam. Several ecological reserves, a zoo and the Taiwanese-Paraguayan Technology Park are situated in this department.

The city of Presidente Franco was the first city founded in this department. Several important agricultural establishments are centered in the region of Minga Guazú which is home of the Guarani International Airport.

In colonial times, there were several settlements established in this area. The most important of these being Ontiveros, Ciudad Real, and Villa Rica del Espíritu Santo. Nevertheless, these villages did not initially prosper due to the constant attacks of the Bandeirantes.

By the end of the 17th century and beginnings of the 18th century, many populations settled in this area due to the promising logging economy. These urban centers organized around military bases that served to defend them against the attacks of the Bandeirantes. Some of these cities exist into the present day, such as: Villa Curuguaty, Ygatimi, Caaguazú, Lima and Ajos.

After the War against the Triple Alliance, these lands were sold, creating large states in which the most important economic activities were the exploitation of the local forests and the cultivation of yerba mate. During the War Against the Triple Alliance many of the men of Paraguay died, and to make up for population loss, European/Middle Eastern and East Asian men immigrated to the nation. In this region, many descendants of Poles, Ukrainians, and Japanese people are found demographically similar to the neighboring Brazilian state of Paraná. There was also settlement of Brazilian from the South of Brazil, most of the people were white Brazilians of Italian, Portuguese, Spanish, German, Eastern European, Arabic blood. And Also Japanese Brazilians and Brazilians of mixed race.

By the end of the 19th century, it was a very active port known as Tacurú Pucú, which means "high termite mound". This port was used for the transport of lumber, through the Paraná River, to Encarnación, and from Encarnación to facilitate the trade of food and textiles. After the TRI
