Empress Thừa Thiên ({{langx|vi|Thừa Thiên Cao Hoàng Hậu}}; {{lang-vi-hantu|{{linktext|承天|高皇|后}}}}, 1762–1814), born Tống Phúc Thị Lan ({{linktext|宋|福|氏|蘭}}), was the first wife of Nguyễn Phúc Ánh (future Emperor Gia Long) and mother of Crown Prince Nguyễn Phúc Cảnh.

She was a daughter of general Tống Phước Khuông of the Nguyễn lords. Nguyễn Ánh married her when he was 18. Empress Thừa Thiên had two sons with Gia Long: Nguyen Phuc Chieu (who died after several days) and Crown Prince Nguyễn Phúc Cảnh. After her death, she was buried at Gia Long's Thiên Thọ tomb, alongside the Emperor.
