The St. Nicholas the Wonderworker Church in Sofia is a Russian Orthodox church and a dependency of the Russian Orthodox Church. From 1907 to 1934, it served as the Russian embassy church.

After the end of the Russo-Turkish War of 1877-1878, a significant Russian community formed in Sofia, mainly consisting of experts. A separate church was planned for them.

In 1882, the city authorities allocated a plot of 1400 square meters on the site of a destroyed market mosque. A committee was created to build the church and began collecting donations. The laying of the church was scheduled for 1902, but was postponed for various reasons, mainly political.

During this time, the Russian community used a hall in the diplomatic agency for prayers.

The laying of the modern church took place on September 2 (15), 1907, in the presence of Grand Duke Vladimir Alexandrovich and Bulgarian Prince Ferdinand with the heir to the throne Boris.

The project was developed by Mikhail Timofeevich Preobrazhensky. By 1911, the building was constructed in rough form, but finishing works and painting continued for more than two years.

When Bulgaria entered World War I on the side of the Central Powers in October 1915, diplomatic relations with Russia were severed, and the Russian clergy evacuated, halting services in the church.

From January 2, 1920, until early 1923, a Russian diplomatic mission of General Anton Denikin's government, led by Alexander Petryaev, operated in Sofia, protecting the interests of Russian refugees and the church in Bulgaria. After its closure, the property of the mission and the church was sealed by a commission appointed by the Bulgarian Ministry of Foreign Affairs and Confessions.

The wall paintings were done in the traditional Russian style under the guidance of V. T. Perminov, with tempera painting in matte tones.

The majolica iconostasis was made in St. Petersburg.

The church bells were gifted by Emperor Nicholas II.

In the church crypt, Archbishop Seraphim (Sobolev) was buried in 1950, and in 1987, his tomb was decorated with marble.
