ISO 3166-2:CO is the entry for Colombia in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces, states or departments) of all countries coded in ISO 3166-1.

Currently for Colombia, ISO 3166-2 codes are defined for 1 capital district and 32 departments. The capital district of Bogotá has special status equal to the departments.

Each code consists of two parts, separated by a hyphen. The first part is CO, the ISO 3166-1 alpha-2 code of Colombia. The second part is either of the following:

• two letters: capital district
• three letters: departments

Subdivision names are listed as in the ISO 3166-2 standard published by the ISO 3166 Maintenance Agency (ISO 3166/MA).

Subdivision names are sorted in traditional Spanish alphabetical order: a-c, ch, d-l, ll, m-n, ñ, o-z.
