The Sacred Heart Cathedral (Serbo-Croatian: Katedrala Srca Isusova/Катедрала Срца Исусова) is a Catholic church in Sarajevo; commonly referred as the Sarajevo Cathedral (Sarajevska katedrala/Сарајевска катедрала), it is the largest cathedral in Bosnia and Herzegovina. It is the seat of the Archbishop of Vrhbosna, currently Tomo Vukšić, and center of Catholic worship in the city. The cathedral is located in the city's Old Town district.

Sacred Heart Cathedral was built in honor of the Sacred Heart of Jesus, an important Catholic concept. The building is in the Neo-Gothic style, with Romanesque Revival elements. The building was awarded to the Viennese contractor Baron Karl Schwarz with supervising architect Josip Vancaš. He modeled it after the Notre-Dame in Dijon (France). Work began on 25 August 1884, and was completed on 9 November 1887. The Bishop of Dubrovnik was present for the consecration on 14 September 1889.

The building was damaged during the Siege of Sarajevo, but not completely destroyed, and the damage has since been repaired. The building is often considered as a symbol of the city: The design above the door to the cathedral is part of the flag and seal of Sarajevo Canton and the Romanesque towers are featured on the flag and coat of arms of Sarajevo.
