Taneti Maamau (born 16 September 1960) is an I-Kiribati politician who has served as the fifth president of Kiribati since 2016. A member of the Tobwaan Kiribati Party, his policies are targeted at strengthening Kiribati's weak economy and alleviating social issues. His government announced the Kiribati Vision for 20 Years (KV20), which plans to develop the tourism and fishing industries with aid from foreign investors.

Maamau's government stopped recognizing Taiwan in favour of closer ties with China, drawing concern from within his own party, the opposition and Western countries. He dismissed his predecessor's "Migration With Dignity" climate change policy. After his reelection in 2020, Maamau unveiled plans to combat rising sea levels by raising Kiribati's islands. This would be partly through dredging and supported by aid from foreign allies such as China. In 2022, Maamau's government was widely criticized for causing a constitutional crisis by suspending all superior court judges. He was re-elected in 2024 to serve a third and final term.

Taneti Maamau was born on 16 September 1960. Hailing from Onotoa, Maamau attended the University of the South Pacific before taking a master's degree at the University of Queensland in Australia. In 2003, he completed his thesis on industrialization and trade policies in India.

In 1997, Maamau began public service as a Planning Officer with the Ministry of Finance and Economic Development. President Teburoro Tito made Maamau the ministry's permanent secretary in the mid-1990s, and Maamau went on to also be secretary of the Ministry of Commerce, Industry and Cooperatives.

In 2002, Maamau resigned from public service to join politics and won one of two seats for Onotoa in 2007. In 2011 and in 2015, he was re-elected a member of the Maneaba ni Maungatabu (parliament). Anote Tong served as president from 2003 to 2016. Maamau was part of the opposition.

After the 2015–16 parliamentary election, the United Coalition and Maurin Kiribati Parties combined to become the Tobwaan Kiribati Party. In February 2016, they endorsed Maamau as their candidate for the presidential election. He also received support from Tito. He won the election and was officially declared President after winning against the ruling party by nearly 60%. He was sworn in on 11 March 2016.

Maamau's policies target economic and social issues. In a legislative session in April, the government announced policy changes which extended free education to year 12. It established a committee to investigate corruption and abuse of power and gave a $1 million grant to the two major Christian churches.

Despite lack of sanitation, employment, and the rising cost of living in the capital of South Tarawa, many I-Kiribati from the outer islands migrate there. Maamau attempted to develop the coconut trade and manufacturing to reduce migration and poverty. In the same session, he doubled the copra subsidy, which ensures a guaranteed price for citizens selling copra to the government, from the $1 per kilo set by Tong. A journalist for Inside Climate News reported that consequently, on Abaiang, there is a smaller supply of coconuts. Copra cutters became fiercely competitive to the point of harvesting unripe crop. The subsidy accounted for 14% of the government's expected annual expenses.
