Queen Anu or Lady Anu (Mongolian: Ану хатан; also known as Ana Dara; birth date unknown - 1696) was granddaughter of Ochirtu Secen Khan of Khoshuud (or his youngest daughter according to some written historical sources), who was the nephew and adopted son of Güshi Khan. She wed prince Sengge, son of Erdeni Batur, regarded as the founder of the Dzungar Khanate. After Sengge's assassination by his half-brothers Tseten and Tsobda Batur in 1670, Anu married Sengge's successor, his brother Galdan Boshughtu Khan (1644-1697), who had spent ten years in Tibet as a Buddhist monk. With troops provided by Ochirtu, Galdan avenged his brother's death and assumed the Dzungar Khanate throne. Anu's marriage to Galdan Boshughtu produced one son, prince Sevdenbaljir, and two daughters, princesses Yunchihai and Boum.
Galdan relied on Anu for counsel throughout his reign as he expanded Dzungar Mongol rule from the west end of the Great Wall of China to present-day eastern Kazakhstan, and from present-day northern Kyrgyzstan to southern Siberia. Fearing the rise of a new Mongol empire, the Qing dynasty sent three armies west towards Mongolia in 1696. The Qing Kangxi Emperor personally led the expeditionary forces. Galdan moved his army south from the Khentii Mountains to meet the Qing army's western column at the Battle of Jao Modo in May 1696, but his troops were soon surrounded by the superior Qing forces.
Anu led a counterattack which enabled her husband to escape from the enemy encirclement. Although Galdan managed to flee with a small remnant of his supporters, Anu was killed by an enemy arrow during her charge. She was buried in the foothills of Khangai mountains in an area now referred to as "Hatant" (place of the queen) in present-day Khotont soum of Arkhangai Province.
