Tyumen Cathedral Mosque, Islamic religious center in Tyumen, Russia.

Tyumen Cathedral Mosque is a stone mosque in the Yanaul area of Tyumen, built on the site of an older wooden mosque. Its pale beige block walls support a flat-roofed lower section with a central arched entrance and arched upper windows. A tall cylindrical minaret with a balcony and conical spire stands on the left, a shorter tower with a crescent at the right corner, and a small drum with a shallow dome above the centre.

The stone mosque was completed in 1997 after eight years of construction, built on the site of an older wooden mosque in the Tatar village of Yanaul, absorbed by Tyumen in the 1970s. Lacking central funding, the work was paid for by Islamic foundations and partly by the city and regional administrations. It is named after Umar ibn al-Khattab, a companion of the Prophet Muhammad.

The mosque serves as a gathering place where the local Muslim community comes together for prayers and religious observances throughout the year. It has become a symbol of religious diversity in the city and reflects the presence of Islam in Siberia.

The mosque lies in the former Tatar village of Yanaul, now the Parfenovo district, about 5 km from central Tyumen. On Fridays more than two thousand worshippers gather, filling the basement hall, the stair landings and the courtyard, so arrive early. The building also houses the residence of the mufti of the Tyumen Region.
