Mastan Babu Malli (3 September 1974 – 24 March 2015) was an Indian mountaineer. He is best known for his 2006 world record creating feat of climbing each continent's highest peak (the Seven Summits) in the shortest span of time at that point - a total of 172 days with the first climb on 19 January 2006 and the seventh on 10 July 2006. This feat made him the fastest seven summiteer in the world at that time, the first Indian and South Asian to climb all seven summits, the first Indian to climb Vinson Massif and the first Indian to climb Carstensz Pyramid. While his record for climbing the seven summits has since been improved upon, his record of attaining each summit on a different day of the week still stands today.
