The Archdiocese of Malacca-Singapore was a Latin archdiocese in Malaysia and Singapore.
It was established as the Diocese of Malacca,[1] [2] and elevated to Archdiocese level in 1953.
In 1955, the Archdiocese of Malacca was split and an ecclesiastical province was formed in its place comprising the Archdiocese of Malacca-Singapore as the metropolitan see and the Diocese of Kuala Lumpur and Diocese of Penang as suffragan dioceses.
In 1972, Archdiocese of Malacca-Singapore was split into the Archdiocese of Singapore and the Diocese of Malacca-Johor. Michel Olçomendy was the archbishop during this entire period. After the split, he continued to serve as Archbishop of Singapore until retiring in 1976.
