Buddhism was introduced in Singapore primarily by migrants from across the world over past centuries. The first recorded histories of Buddhism in Singapore can be observed in the early days' monasteries and temples, in particularly Asia.

Buddhism first appeared around the Singapore Straits during the 2nd century. Given the historic status of Singapore as a British trade port and colonial state, as well as a brief period of Japanese colonial rule during World War II, over the centuries a variety of Buddhist lineages from across the globe has appeared gradually on the island. They include Japanese and Western interpretations of the tripitaka, although a substantial local presence have their origins dating back into historic South East and East Asian kingdoms.

With the advent of religious freedom in modern-day Singapore, most Singaporeans that adhere to the Buddhist doctrine are a participant of at least one Buddhist organisation, while also being actively involved in other beliefs that are presented across the diverse cosmopolitan culture. There is also an active female involvement in Singaporean Buddhism, which includes lay female followers as well as monastic nuns. Buddhists generally classify themselves as either Theravada or Mahayana.
