List of best-selling singles in South Korea

In 2010, the Korea Music Content Industry Association (KMCA) established the Gaon Chart, a weekly record chart that tabulates both physical and digital music sales. Gaon first published digital download figures for songs in February 2011, when it released a list of the best-selling songs of 2010. On March 11, 2011, Gaon began publishing the weekly Gaon Download Chart, which included sales figures for songs. Gaon stopped releasing weekly sales figures for songs in 2018 and introduced a certification system that recognizes songs that reach at least 2.5 million downloads. The chart (renamed the Circle Chart in 2022) also periodically reports sales figures for songs released before the introduction of the certification system. ==List of best-selling singles==
