The name Sione has its origins in the Tongan language, spoken by the indigenous people of the Pacific island nation of Tonga. It is a masculine given name that dates back several centuries, with records indicating its use as early as the 16th century. The name is believed to be derived from the Tongan word "sio," which means "to see" or "to look."
