This is a list of ambassadors, high commissioners and permanent representatives of the Republic of Singapore to other countries and international organisations.
The term high commission is used to refer to the diplomatic mission of one former British colony - or the United Kingdom - in another (i.e. diplomatic missions within the Commonwealth of Nations).
A permanent representative heads a diplomatic mission to an international organisation.
NRAs/NRHCs are resident in Singapore, but make regular representational visits to their country of accreditation.
When on representational visits or while performing other official duties, NRAs/NRHCs have the same powers and authority as resident heads of mission.
