Saint Mary's Cathedral or Immaculate Conception Cathedral is a Catholic cathedral located on Bo Aung Kyaw Street in Botahtaung Township, Yangon, Burma. The cathedral's exterior, of red brick, consists of spires and a bell tower. It was designed by Dutch architect Joseph Cuypers, son of Pierre Cuypers.
The cathedral is the largest in Burma. Located on the grounds of the cathedral is Basic Education High School No. 6, which is locally known as "Saint Paul's High School", although it has no religious affiliation with the Catholic Church today.
