Malaysia competed at the 2012 Summer Olympics in London, from 27 July to 12 August 2012. This was the nation's fourteenth appearance at the Olympics, although it had previously competed in two other games under the name Malaya. Malaysia did not participate at the 1980 Summer Olympics in Moscow, because of its partial support to the United States boycott. Ahmad Sarji Abdul Hamid was the Chef de Mission of the national delegation at the Games.
