The Church of Saint Equal-to-the-Apostles Prince Vladimir is an Orthodox church in the town of Mariánské Lázně, formerly known as Marienbad. The church belongs to the Karlovy Vary presbytery of the Prague Diocese of the Orthodox Church of the Czech Lands and Slovakia, and its rector is Archpriest Josef Hauzar.

The idea of building an Orthodox church in Marienbad arose in 1825 among Russian vacationers who began fundraising. However, the project could not be realized, and the funds were directed towards the construction of a Catholic church of the Ascension of the Virgin Mary. In 1860, a small chapel was organized in one of the buildings, which in 1878 was moved to the first floor of the town hall. In November 1880, a "field" Nikolskaya church was installed there, which was later transferred to Nice. On July 15 (27), 1882, a new church was consecrated, where services were conducted by a priest from Weimar during the resort season.

In 1881, a committee was formed to build a separate church, which organized fundraising. In 1891, the bank where the deposits were held went bankrupt, but a new committee gathered a significant amount. The chairman of the Church Building Committee in St. Petersburg was Count I. I. Vorontsov-Dashkov. In July 1899, a plot of land of about 800 square meters was chosen for the construction of the church on the wooded slope of the Sukhý Vršek hill, between the "Casino" hotel and the Anglican church.

The laying of the church took place on July 11 (23), 1900, and the consecration was held on June 25 (July 8), 1902, under the guidance of Archpriest Alexey Maltsev. The construction was carried out by Gustav Widerman, and the project was developed by N. V. Sultanov. The church did not have its own parish and was attached to the Dresden church, and from 1906, to the Weimar church. With the onset of World War I, services became rare.

In the 1920s and 1930s, the church was under the jurisdiction of the Prague bishop Sergey (Korolev), and services were conducted only in the summer. After the establishment of the Protectorate of Bohemia and Moravia, the parish and its property were transferred to the Berlin and German Diocese of the Russian Orthodox Church Outside Russia by the order of Reich Minister of Church Affairs Hans Kerrl on May 5, 1939. During World War II, several Orthodox clergy served in the church, including Archbishop Alexander (Inozemtsev).

A regular Orthodox parish was formed in 1945 when settlers, Orthodox Czechs from Volhynia, arrived in the region. In the same year, the church passed to the Western European Exarchate of the Moscow Patriarchate, and from 1946, to the Czechoslovak Exarchate. With the granting of autocephaly in 1951 to the Czechoslovak Orthodox Church, the church came under its jurisdiction.

In 1990, an Orthodox faculty of theology was established at the church.
