John Rhys-Davies was born in Salisbury on 5 May 1944, the son of Welsh parents. His mother, Phyllis Jones, was a nurse, while his father, Rhys Davies, was a mechanical engineer and colonial officer.

Due to his father's work as a colonial police officer, Rhys-Davies was raised in Tanganyika (today part of Tanzania) before his family moved to the Welsh town of Ammanford. While in Tanganyika, his family lived in places such as Dar es Salaam, Kongwa, Moshi, and Mwanza. Rhys-Davies was educated at independent Truro School in Cornwall and then at the University of East Anglia, where he was one of the first 105 students admitted and became a co-founder of its drama club. After a stint teaching at a secondary school in Watton, Norfolk, Rhys-Davies won a place at the Royal Academy of Dramatic Art in London.
