The Colombian Geological Survey (CGS) (Spanish: Servicio Geológico Colombiano;[3] formerly known as INGEOMINAS) is a scientific agency of the Colombian government in charge of contributing to the socioeconomic development of the nation through research in basic and applied geosciences of the subsoil, the potential of its resources, evaluating and monitoring threats of geological origin, managing the geoscientific knowledge of the nation, and studying the nuclear and radioactive elements in Colombia.

[7] In 1968 the Instituto Nacional de Investigaciones Geológico-Mineras (INGEOMINAS) was formed by combining the Geological Service, the Mining Inventory, and the National Chemical Laboratory.

In 2011 INGEOMINAS leaves all matters of mining to newly formed Agencia Nacional de Minería and attains the name Servicio Geológico Colombiano (SGC).

[11] The Colombian Geological Survey runs a network of museums located in Bogotá, Medellín, and Cali which are named after José Royo y Gómez, a Spaniard geologist who was forced into exile in Colombia during the Spanish Civil War.

Throughout José Royo y Gómez' time at the SGNC, he directed various commissions where he continued his investigations and promoting the study of natural sciences in Colombia.
