Grupo Empresarial Antioqueño

The Grupo Empresarial Antioqueño (GEA, Business Group of Antioquia) also known as Sindicato Antioqueño, is a Colombian conglomerate composed by around 125 companies, most of them based in Antioquia Department.

Though, legally speaking, such an entity does not exist, it is commonly regarded as the first Colombian keiretsu. It is "controlled" by four main companies: Bancolombia (banking), Grupo Argos (cement, power & infrastructure), Grupo Sura (insurance, financial), and Grupo Nutresa (processed food). The group, through these companies, has 10,000 shareholders. GEA's 2007 income amounts to 5.5% of Colombia's gross domestic product.

On January 15, 2023, the Financial Times reported: 'Regulators are investigating whether the GEA is acting as an “economic group”.'
