The Basilica of the National Vow (Spanish: Basílica del Voto Nacional) is a Roman Catholic church located in the historic center of Quito, Ecuador.

The basilica arose from the idea, proposed by Father Julio Matovelle in 1883, of building a monument as a perpetual reminder of the consecration of Ecuador to the Sacred Heart.

By the decree of July 3, 1885, the fourth Quitense Provincial Council turned the construction of the basilica into a religious commitment in the name of the country.

In 1901, Father Matovelle and his Community of Missionary Monks, took charge of the construction at the request of Archbishop Pedro Rafael González Calisto.

The basilica was blessed by Pope John Paul II on January 30, 1985, and it was consecrated[1] and inaugurated on July 12, 1988.
