Cathedral of St John The Evangelist is the mother church of the Roman Catholic Archdiocese of Kuala Lumpur and the seat of its Archbishop, Julian Leow Beng Kim.

The first church on a nearby site was established in 1883, and consisted of a long wooden hall with a few windows built on a forested area of Bukit Nanas,[3] and was dedicated to St John the Evangelist.

It has however been converted into the Archdiocese of Kuala Lumpur Museum which will commence operations in 2025 and is currently undergoing restoration of its original stained glass windows and high altar.

Situated in the heart of the Kuala Lumpur, the cathedral also draws many foreign visitors and diplomats, apart from the regular parishioners, to its Sunday services.

Father Gerard Theraviam announced that masses would be suspended at the cathedral and would transfer to Convent Bukit Nanas chapel until further notice.
