The Leventina District is one of the eight districts of the largely Italian-speaking canton of Ticino in Switzerland. The capital of the district is Faido but the largest town is Airolo on the southern flank of the Gotthard Pass.
Situated to the north of the canton, its territory covers the area of the Ticino River as far south as Biasca, in particular the Bedretto Valley and the Leventina Valley.
Leventina is divided into four sub-districts, termed 'circles', and a total area of 479.57 km2 with a population of 8,827. Its capital is the municipality of Faido. The valley became part of Switzerland on 5 March 1480, following the treaty of Lucerne with the Duchy of Milan.
