Fiamē Mataʻafa Faumuina Mulinuʻu II CBE (5 August 1921 – 20 May 1975) was a Western Samoan paramount chief and politician.

The holder of the Mataʻafa title, one of the four main Samoan chieftainships, he became the first prime minister of Western Samoa in 1959, serving until 1970.

It was reported that he would have probably won in the second round (which was tied at 23 votes each) if one of his supporters, To'omata Lilomaiava Tua, had not died the previous week.

[9] In February 1966, Mata'afa ordered that the sport of cricket be banned on every day except Wednesdays and Saturdays, because of the "lackadaisical approach" taken to the clean-up after a cyclone.

[10] Following the 1973 elections, Mata'afa returned as Prime Minister, defeating Lealofi and Tupuola Efi in the first round of voting.
