Holy Spirit Cathedral, Saratov, Orthodox cathedral in Saratov, Russia.

Holy Spirit Cathedral is an Orthodox place of worship topped by five domes finished in silver and blue, displaying classic Russian Orthodox architecture throughout. The interior is richly decorated with religious iconography and religious furnishings that serve the congregation's spiritual needs.

The first newspaper mention of a Holy Spirit church in Saratov dates to 1844. In 1855, merchant Pyotr Tyulpin funded a stone church and bell tower on the site of a wooden building; Bishop Ioannikiy consecrated it in 1858. Closed in 1939 and used as a grain store, it reopened in December 1947, and the main altar was reconsecrated in 1948.

The church keeps the name Cathedral (sobor) in everyday use even after the title passed to Trinity Cathedral in 2014. Its side chapels were consecrated in 1995: the right to St Nicholas, the left to the Mother of God icon "The Sign". A chapel of the "Life-Giving Spring" icon is attached to it at remand prison No. 1.

The cathedral is located in central Saratov and is easy to reach on foot from the main city areas. Visitors should dress modestly and observe silence during services, as the space remains active for daily worship and prayer.

In 1931 the church's bells were confiscated for industrial use, so no historic bell survives here. The building itself was closed in 1939 and used as a grain store; on 13 June 1941 the city executive committee considered converting it into a cinema, a plan stopped by the German invasion of 22 June.
