Mustapha Dinguizli (Arabic: مصطفى الدنقزلي), (27 August 1865 – 20 October 1926) was a Tunisian politician.

After Ghileb's death, Dinguizli succeeded his uncle as head of the municipality of Tunis between 1912 and 1915.

Pursuing a conciliatory policy with the authorities of the French protectorate of Tunisia, Dinguizli remained at his post until his death in 1926.

He is among the ministers buried in the mausoleum of Tourbet el Bey located in the medina of Tunis.

[1] His brother Bechir Dinguizli became the first Tunisian Muslim to become a doctor in the modern era.
