Kalkot Mataskelekele Mauliliu (born 24 April 1949) is a Vanuatuan politician who served as the president of Vanuatu from 16 August 2004 to 16 August 2009.
He was elected by the electoral college, which consists of the Parliament and regional Presidents, on 16 August 2004, and sworn in the same day.
He had previously been a candidate in the presidential election of April 2004, and was backed by the government of Edward Natapei. However, after several inconclusive rounds in the electoral college, he was defeated by Alfred Maseng. After the impeachment of Maseng and a parliamentary election, a new election was held on 12 August 2004, which was inconclusive and was continued on 16 August. Though Kalkot was widely expected to win, there were many other candidates, and he faced tough opposition from Willie David Saul and former Prime Minister Donald Kalpokas. In the final round of voting, Kalkot defeated Saul by a vote of 49 to 7.
