Lê Thị Ngọc Bình (黎氏玉評, 1785 – 1810) was the Annamese princess, youngest daughter of Emperor Lê Hiển Tông of Revival Lê dynasty. Her early life was unknown, when the Tây Sơn dynasty succeeded Lê Dynasty as the official dynasty of Annam ; Emperor Quang Trung ordered his Crown Prince Nguyễn Quang Toản (later Emperor Cảnh Thịnh) to marry her.
In 1801, lord Nguyễn Ánh's force, main rival of Tây Sơn, captured Phú Xuân and forced Cảnh Thịnh flee to Tonkin and left Lê Thị Ngọc Bình and his wives behind. Nguyễn Ánh captured but did not threaten Bình; then Ánh married her regardless of dissuasions of his followers.
Later, Nguyễn Ánh became Emperor Nguyễn Thế Tổ and gave her the royal title Third Concubine (Đệ-tam Cung). Bình had with emperor Nguyễn Thế Tổ four children : Prince Nguyen Phước Quan, prince Nguyen Phước Cu, princess An Nghia Ngoc Ngon, and princess My Khue Ngoc Khue. Le Thi Ngoc Binh died in 1810 and was buried in Trúc Lâm, Thừa Thiên Huế.
