John Henry Kilbuck (May 15, 1861 – 1922) — sometimes spelled Killbuck (Lenape)— and his wife, Edith Kilbuck (née Romig; April 16, 1865 – 1933), were Moravian missionaries in southwestern Alaska in the late 19th and early 20th centuries. John H. Kilbuck was the first Lenape to be ordained as a Moravian minister. They served the Yup'ik, used their language in the Moravian Church in their area, and supported development of a writing system for Yup'ik.
