ISO 639-5 (ISO 639-5:2008), titled "Codes for the representation of names of languages – Part 5: Alpha-3 code for language families and groups", is an international-standard developed by ISO/TC 37/SC 2. The international standard was published on 2008-05-15.

This part of ISO 639 defines alpha-3 (3 letter) codes for language families. Some of its codes are contained in ISO 639-2, and some are only in ISO 639-5. As of the update on 2008-10-29 there were 114 codes defined.

ISO 639-2 contains codes for some individual and group languages and so any code in it is either in 639-3 or 639-5. Languages, families, or groups codes in ISO 639-2 can be of type "group" (g) or "rest group" (r), where a "group" consists of several related languages, while a "rest group" is a group of several related languages, from which some specific languages have been excluded. In ISO 639-5, the "rest groups" have been redefined to cover its entire group; thus, their meaning cannot be ascertained without knowing whether they are used in their ISO 639-2 meaning or their ISO 639-5 meaning.

Examples of the relation to ISO 639-2:

• has ISO 639-2 code, is rest group (r):
  • e.g. afa in 639-2 it covers only "Afro-Asiatic languages (Other)", in 639-5 it covers all "Afro-Asiatic languages"
• has ISO 639-2 code, is normal group (g):
  • e.g. alg in 639-2 and 639-5 it covers all Algonquian languages
• no ISO 639-2 code (-):
  • e.g. Albanian languages - sqj
