Brigitta Christina Scherzenfeldt, as married Bernow, Lindström, Ziems, and Renat (1684 – 4 April 1736), was a Swedish memoirist and weaving teacher who was captured during the Great Northern War and lived as a slave over 15 years in the Dzungar Khanate in Central Asia. She dictated her memoirs, describing her life as a slave, after her release. Her story is regarded as a unique source of information about life among the Dzungars.
