Theodora of Sihla, also known as Teodora or Bohdanna of the Carpathians, was a Christian ascetic and Romanian Orthodox saint born around 1650. She was commemorated on 7 August. Theodora's early life was marked by her marriage against her will and her subsequent decision, along with her husband, to embrace monasticism. She then retreated into the Buzău Mountains and later became an anchorite in the Sihla wilderness. After her death, her body remained in the cave where she had spent most of her hermitage. The knowledge of her life and death reached her husband, who spent the last decade of his life close to her resting place. The Sihla Monastery was founded in her memory, and she was later translated to Pechersk Lavra in Kiev. The Romanian Orthodox Church canonized her on 20 June 1992, establishing her commemoration on 7 August. Theodora's life is celebrated for her dedication to asceticism and her enduring legacy as a saint in the Romanian Orthodox tradition.
