Gustaf Albert Ahlbert (26 January 1884 – 1943) was a Swedish missionary and linguist. He served with the Mission Union of Sweden in Chinese Turkestan (present day Xinjiang). Ahlbert had a competent knowledge of Hebrew, Greek, Arabic and Uyghur. He was one of the last three missionaries to be expelled from Kashgar in 1939. After he was expelled, he worked among Muslims in India, and worked together with Oskar Hermansson and Dr. Nur Luke on the Uyghur Bible translation, until his death in Bombay in 1943.
