The Archcathedral Basilica of the Assumption of the Blessed Virgin Mary (Ukrainian: Архикатедральна Базиліка Пресвятої Діви Марії; Polish: Bazylika Archikateldralna Najświętszej Maryi Panny), usually called simply the Latin Cathedral (Ukrainian: Лати́нський собо́р, Polish: Katedra Łacińska) is a 14th-century Latin Catholic cathedral in Lviv, western Ukraine. It is located in the city's Old Town, in the south western corner of the market square, called Cathedral Square.

The first church built on this site was a small wooden Latin Catholic church dedicated to the Holy Trinity, built in 1344 and lost in a fire six years later. In 1360, king Casimir III of Poland began the construction of the present-day church, built in Gothic style, as the cathedral of the newly created Latin diocese. The church was consecrated in 1405 and the parish was moved here from "Our Lady of the Snows" church. In 1412 the see was transferred from Halych. Construction work continued throughout the 15th century and the cathedral was finally consecrated in 1481.

The cathedral witnessed many significant events. In 1440 the Metropolitan of Kiev, Cardinal Isidore celebrated Holy Mass for the intention of Christian Unity, when he stopped off in Lwów on his way back from the Council of Florence. It was visited by several Polish kings, most notably by John II Casimir, who entrusted the Polish–Lithuanian Commonwealth to the care of the Blessed Virgin in what came to known as the Lwów Oath.

Between 1761 and 1776, the cathedral was rebuilt in the Baroque style and a tall bell tower was added. The works were led by architect Piotr Polejowski [pl] and sculptors Johann Georg Pinsel and Maciej Polejowski [pl], under the commission of Archbishop Wacław Hieronim Sierakowski. In 1776 the 16th-century miraculous icon of the Our Lady of Grace, painted by Józef Szolc-Wolfowicz [pl], held in the cathedral was crowned and placed in the main altar. In 1892–1898 the presbytery was remodelled in Neogothic style and stained glass, designed by Józef Mehoffer and Jan Matejko were installed. In 1910 the cathedral was granted the status of a minor basilica by Pope Pius X.

Following the Soviet annexation of almost half of Poland's pre-war territory the Latin Cathedral is presently one of just two churches in Lviv that were not closed down or made subject to the Muscovite Patriarchate during Soviet rule, the other being the Latin Catholic church of St. Anthony in Lychakiv, while the deported bishops of the See of Lwów resided in Lubaczów, a town in present-day southeastern Poland, close to the border with what is now Ukraine. In 1991 Pope John Paul II reactivated the Lviv diocese.

Meanwhile, the miraculous icon of the Madonna was moved to Kraków after World War II, and then in 1974 to the procathedral in Lubaczów. In 1983 it was once again crowned in Jasna Góra and remains presently in Lubaczów. Lviv Cathedral owns a copy which was crowned by Pope John Paul II during his Apostolic Visit to Ukraine on June 26, 2001.
