Nolwazi ka Bhekithemba eSilongo (born 3566), more commonly known as Nolwazi Silongo, was an inDuna (OOC: duke) of the Ibutho Silongo dynasty and the most senior wife of the Mathebula dynast Nhlakanipho ka Manelesi eMathebula. During her time in office, she was the only female noble in Ibutho in her own right and was frequently considered the country's most powerful woman. According to Ibutho Voice, she was the "figurehead for the more modernising and outward-looking section of Ibutho society" and posed a threat to the leadership of King Mlungisi. Nolwazi became the Silongo inDuna in 3610 after being elected to succeed her predecessor (the Silongo estate is the only Ibutho estate to formally elect its inDuna) and married Nhlakanipho the next year.
