Agafia Karpovna Lykova (; born 17 April 1944) is a Russian Old Believer, part of the Lykov family, who has lived alone in the taiga for most of her life. As of 2016, she resides in the Western Sayan mountains, in the Republic of Khakassia. Lykova became a national phenomenon in the early 1980s when Vasily Peskov published articles about her family and their extreme isolation from the rest of society. Lykova is the sole surviving member of the family and has been mostly self-sufficient since 1988, when her father died.
