This list of diplomatic missions in Singapore is made up of 75 embassies/high commissions, several foreign consular posts and 11 international organisations. It does not include honorary consuls. Countries without any forms of diplomatic representations in Singapore have accredited non-resident ambassadors or high commissioners to the island city-state.
Due to the high cost of land for rent in Singapore, many countries operate their embassies or high commissions in an office unit within a commercial building. Nevertheless, there are countries that have chanceries to house their missions, namely Australia, Brunei, China, France, Germany, India, Indonesia, Israel, Kuwait, Malaysia, Philippines, Russia, Sweden, Switzerland, Thailand, United Kingdom, United States, and Vietnam.
