ISO 3166-2:BA is the entry for Bosnia and Herzegovina 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 or states) of all countries coded in ISO 3166-1.

Currently for Bosnia and Herzegovina, ISO 3166-2 codes are defined for 2 entities and 1 district with special status. The Brčko District has special status, formally belonging to both entities but effectively self-governing.

Each code consists of two parts, separated by a hyphen. The first part is BA, the ISO 3166-1 alpha-2 code of Bosnia and Herzegovina. The second part is three letters.

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

ISO 639-1 codes are used to represent subdivision names in the following administrative languages:

• (bs): Bosnian
• (hr): Croatian
• (sr): Serbian using UN III/11 1977 romanization
