Trúc Lâm Yên Tử (竹林安子), or simply Trúc Lâm ("Bamboo Grove"), is a Vietnamese Thiền (i.e. zen) sect. It is the only native school of Buddhism in Vietnam. The school was founded by Emperor Trần Nhân Tông (1258–1308) showing influence from Confucian and Taoist philosophy. Trúc Lâm's prestige later waned as Confucianism became dominant in the royal court.
A revival was attempted by later adherents including Ngô Thì Nhậm (1746–1803) during the Tay Son dynasty. Nhậm attempted to harmonize the "Three teachings" of Buddhism, Confucianism and Taoism.
