Rovio is a former municipality in the district of Lugano in the canton of Ticino in Switzerland. Traditionally Rovio has been an agricultural community, raising livestock and growing vines, but today many of its houses are occupied by commuters, largely travelling into the city of Lugano. The entire village of Rovio is part of the Inventory of Swiss Heritage Sites, whilst the oratory of S. Vigilio is listed as a Swiss heritage site of national significance.
