The Bulgarian Academy of Sciences (abbreviated BAS; Bulgarian: Българска академия на науките, Bŭlgarska akademiya na naukite, abbreviated БАН) is the National Academy of Bulgaria, established in 1869.

[1] As Bulgaria was part of the Ottoman Empire, Bulgarian émigrés founded the Bulgarian Literary Society on 26 September 1869, in Brăila in the Kingdom of Romania, on the model of the Romanian Literary Society, that had been established in 1866.

[3] The Bulgarian Literary Society adopted its present-day name in 1911, and Ivan Geshov became the Academy's first president.

The BAS was awarded the Japanese Foreign Minister’s Commendation for their contributions to promotion of mutual understanding between Bulgaria and Japan on 1 December 2020.

Academia Peak and Camp Academia on Livingston Island in the South Shetland Islands, Antarctica are named for the Bulgarian Academy of Sciences in appreciation of Academy's contribution to the Antarctic exploration.
