The Frauenkirche (IPA: [ˈfʁaʊənˌkɪʁçə], Church of Our Lady) is a Lutheran church in Dresden, the capital of the German state of Saxony. Destroyed during the Allied firebombing of Dresden towards the end of World War II, the church was reconstructed between 1994 and 2005.

The current structure is the third church building to stand at this site. The earliest was founded as a Catholic church before being converted to Protestantism during the Reformation. It was replaced in the 18th century by a larger Baroque purpose-built Lutheran building. When its foundation stone was laid on 26 August 1726, it contained a copy of the Augsburg Confession which is primary confession of faith of the Evangelical Lutheran Church. Considered an outstanding example of Protestant sacred architecture, it featured one of the largest domes in Europe. It was originally built as a sign of the will of the citizens of Dresden to remain Protestant after their ruler had converted to Catholicism. Having been reconstructed, it now also serves as a symbol of reconciliation between former warring enemies.

After the destruction of the church in 1945, the remaining ruins were left for nearly half a century as a war memorial, following decisions of local East German leaders. Following the reunification of Germany, it was decided to rebuild the church, starting in 1994. The reconstruction of its exterior was completed in 2004, and the interior the following year. The church was reconsecrated on 30 October 2005 with festive services lasting through the Protestant observance of Reformation Day on 31 October. The surrounding Neumarkt square with its many valuable baroque buildings was also reconstructed in 2004.

The Frauenkirche is often called a cathedral, but it is not the seat of a bishop; the church of the Landesbischof of the Evangelical-Lutheran Church of Saxony is the Church of the Cross. Once a month, an Anglican Evensong is held in English, by clergy from St. George's Anglican Church, Berlin.
