The 2013 Commonwealth Heads of Government Meeting was the 23rd Meeting of the Heads of Government of the Commonwealth of Nations. It was held in Colombo, Sri Lanka, from 15 to 17 November 2013. Commonwealth leaders agreed on Sri Lanka as the 2013 host for the meeting when they met in Port of Spain, Trinidad and Tobago, in 2009. Sri Lanka, which was originally slated to host the summit in 2011, was accused of committing atrocities during the Sri Lankan civil war and the summit was instead held in Perth, Australia; Colombo was given the 2013 summit instead. The leaders of Canada, Mauritius, and India boycotted the summit, citing alleged human rights violations by Sri Lanka against its Tamil minority. Protests were also banned during the summit. President Mahinda Rajapaksa summarised the summit's events as: "Issues covered in the communique include development, political values, global threats, challenges and Commonwealth cooperation." However, the meeting was overshadowed by controversy over Sri Lanka's human rights record and the alleged war crimes during the final stages of the civil war. This was the first time in 40 years that the Head of the Commonwealth, Queen Elizabeth II, was not present at the CHOGM.

The Commonwealth Heads of Government Meeting is a biennial summit meeting of the governmental leaders from all Commonwealth nations. Despite the name, the head of state may be present in the meeting instead of the head of government, especially among semi-presidential states. Every two years the meeting is held in a different member state and is chaired by that nation's respective prime minister or president, who becomes the Commonwealth Chair-in-Office until the next meeting. Queen Elizabeth II, who was the Head of the Commonwealth, attended every CHOGM beginning with Ottawa in 1973 until Perth in 2011, although her formal participation only began in 1997. She was represented by the Prince of Wales at the 2013 meeting as the 87-year-old monarch was curtailing long-distance travel. The Queen attended the 2015 summit in Malta and the 2018 summit in London, but was represented again by the Prince of Wales at the 2022 meeting in Rwanda.
