Casablanca Cathedral, also known as the Church of the Sacred Heart of Jesus, is a Catholic cathedral located in the city of Casablanca, Morocco. It was built in the early 20th century during the French colonial period and served as the primary Catholic church in the city until the 1950s.

The cathedral was designed by French architect Paul Tournon, who was inspired by a mix of Gothic and Art Deco styles. The interior of the cathedral features stained glass windows, mosaics, and paintings. The high altar is made of white marble, and the pulpit and confessionals are made of richly carved wood.

After Morocco gained independence from France in 1956, the cathedral was no longer used for religious purposes and was abandoned. In the 1990s, the Moroccan government began a restoration project to transform the cathedral into a cultural center. It is now used for art exhibitions, concerts, and other cultural events.

Casablanca Cathedral is considered a symbol of the city's history and architecture and is a popular tourist attraction in Casablanca.
