Mahamasina Municipal Stadium, National stadium in Antananarivo, Madagascar.

Kianja Barea Mahamasina is a multi-purpose stadium in the Mahamasina arrondissement of Antananarivo, used for football, rugby, athletics and concerts. Its architecture draws on the shape of the ravinala (traveller's palm) and the hills of Imerina. The rebuilt stands hold 40,260 seated spectators, making it the largest stadium in Madagascar.

A 3,000-seat stadium was built here after Madagascar became a colony in 1897, and it was not renovated before independence in 1960. Four renovations followed from the late 1970s, including the one begun in 2020 after Madagascar qualified for CAN 2019. The rebuilt stadium reopened on 2 September 2021, and it hosts the 26 June national day parade and presidential investitures.

This venue serves as a gathering place where people from across the country come together for football matches, concerts, and national celebrations. The stadium creates moments of shared pride and connection when crowds assemble to cheer for their teams and nation.

The venue is located near Lake Anosy and provides six different entry points to help manage visitor flow efficiently. It is advisable to arrive early to avoid long queues and to have sufficient time to explore the grounds.

The stadium's architecture draws on the shape of the ravinala (traveller's palm) and the hills of Imerina. Its name, Kianja Barea, honours Madagascar's national football team, the Barea. The rebuilt venue was inaugurated on 4 September 2021 in the presence of President Andry Rajoelina and guest Samuel Eto'o.
