索布扎二世（Sobhuza II，1899年7月22日－1982年8月21日），斯威士兰独立后第一任国王。

索布札二世生于1899年7月22日，他的父亲Ngwane V在同年12月10日过世，使年仅数个月的索布札二世便继承了王位，他也是可确认的世界历史中，在位最久的君主。由于继位时过于年幼，前期由他祖母Labotsibeni Mdluli代为摄政，直到1921年12月22日正式加冕亲政。但此时斯威士兰是英国的附庸，1968年宣布独立后才是真正的国家元首。

Sobhuza II, KBE (also known as Nkhotfotjeni, Mona ) (22 July 1899 – 21 August 1982) was the Paramount Chief and later King of Swaziland for 82 years, the longest verifiable reign of any monarch in recorded history. Sobhuza was born on 22 July 1899 at Zombodze Royal Residence, the son of Inkhosikati Lomawa Ndwandwe and King Ngwane V. When he was only four months old, his father died suddenly while dancing incwala. Sobhuza was chosen King soon after that and his grandmother Labotsibeni and his uncle Prince Malunge led the Swazi nation until his maturity in 1921. Sobhuza led Swaziland through independence until his death in 1982. He was succeeded by Mswati III, his young son with Inkhosikati Ntfombi Tfwala, who was crowned in 1986.
