Saint Sophie Ukrainian Orthodox Cathedral, Byzantine Revival cathedral in Montreal, Canada.

Saint Sophie Ukrainian Orthodox Cathedral is a Byzantine Revival church at the corner of Saint-Michel Boulevard and De Bellechasse Street in Rosemont–La Petite-Patrie. Designed by architect Volodymyr Sichynsky and built from 1960 to 1962, it has a stone front facade, brick exterior walls and a copper roof. Its design was modelled on Saint Vladimir's Cathedral in Kyiv.

The cathedral was built in 1962, marking an important moment for the religious and cultural establishment of Montreal's Ukrainian community. Its construction reflected the growing needs and presence of Ukrainian immigrants in the city.

The parish was formed in 1925, when 15 people joined to create the Ukrainian Orthodox Brotherhood; the name Sophy means "Divine Wisdom". Besides worship, the cathedral works as a Ukrainian cultural centre, with a Sunday school for children aged 5 and over in the parish hall and a holiday camp for young people.

The cathedral stands at the corner of Saint-Michel Boulevard and De Bellechasse Street in Rosemont–La Petite-Patrie, not at 12th Avenue. Divine Liturgy is served in Ukrainian at 10:00 a.m. on Sundays and 9:30 a.m. on weekdays; Sunday School for children aged five and over meets at 10:00 a.m. in the Parish Hall. Bilingual Ukrainian-English services are held on special holidays.

The interior features detailed religious icons and murals arranged according to traditional Orthodox ecclesiastical patterns. These artworks create an authentic liturgical environment that reflects the specific spiritual practices of this faith.
