Mauu Siaosi Puepuemai (born ca. 1972) is a Samoan politician and Cabinet Minister. He is a member of the Faʻatuatua i le Atua Samoa ua Tasi (FAST) party.
Mauu was raised in Fagaloa before moving to American Samoa. After returning to Samoa in the 1990s he opened a pizza shop, car rental business, and kava farm. He was first elected to the Legislative Assembly of Samoa in the April 2021 Samoan general election, defeating four other candidates to win the seat of Vaa o Fonoti.
Mau resigned from the HRPP on 25 November 2022 to become an independent, citing a request to do so by his constituents. Following a court challenge, their seats were declared vacant on 19 July 2023. He was subsequently endorsed as a FAST candidate in the resulting by-election. Mauʻu won with a commanding majority. His win, along with FAST victories in the simultaneous by-elections in the Siʻumu and Faleata No. 4 constituencies, handed FAST a two-thirds majority in parliament. Mauʻu was sworn back into parliament on 24 October 2023.
On 15 January 2025 he was appointed Minister of Communications and Information Technology following the sacking of Toelupe Poumulinuku Onesemo.
He contested the 2025 Samoan general election as an independent.
