The Grand Spanish Temple (Romanian: Templul Mare Spaniol), also known as the Cahal Grande (Romanian: Marele templu sefard Cahal Grande), was a former Orthodox Jewish congregation and synagogue, located at 12 Negru Vodă Street, in the Văcărești district of Bucharest, Romania. The synagogue was completed in 1818 and demolished in 1985.

The building is believed to have been "one of the most beautiful Jewish buildings in Bucharest".

The synagogue was built in 1818. The building was devastated by the far-right Legionaries in 1941. The synagogue was rebuilt after the war. However, in 1985 the building, along with the Malbim Synagogue and the Spanish Small Temple, was demolished to make room for the Union Boulevard in Bucharest.
