William Williams (11 February 1859 – 22 April 1892) was a Welsh Presbyterian missionary to Khasi Hills, northeast India, in the late 19th century. He was a son of a ship captain in Nanternis, a small village in Wales. Following his father's footstep he became a sailor for five years. Then he took a profession in carpentry for two years. After graduating in theology from East London Missionary Training Institute (now Cliff College) he became a pastor. Pursuing his ambition he became a missionary of the Welsh Calvinistic Methodist Foreign Mission to Khasi people in India from 1887 until his death. He died of typhoid in 1892.
