List of IOC country codes
The International Olympic Committee (IOC) uses three-letter abbreviation country codes to refer to each group of athletes that participate in the Olympic Games. Each geocode usually identifies a National Olympic Committee (NOC), but there are several codes that have been used for other instances in past Games, such as teams composed of athletes from multiple nations, or groups of athletes not formally representing any nation.
Several of the IOC codes are different from the standard ISO 3166-1 alpha-3 codes. Other sporting organisations like FIFA use similar country codes to refer to their respective teams, but with some differences. Still others, such as the Commonwealth Games Federation or Association of Tennis Professionals, use the IOC list verbatim.
The 1956 Winter Olympics and 1960 Summer Olympics were the first Games to feature Initials of Nations to refer to each NOC in the published official reports. However, the codes used at the next few Games were often based on the host nation's language (e.g., GIA for Japan at the 1956 Winter Olympics and 1960 Summer Olympics, both held in Italy, from Italian Giappone) or based on the French name for the nation (e.g., AUT for Austria, from Autriche). By the 1972 Winter Olympics, most codes were standardized on the current usage, but several have changed in recent years. Additionally, the dissolution of the Soviet Union, division and unification of Germany, breakup of Yugoslavia, dissolution of Czechoslovakia, and several other instances of geographical renaming have all resulted in code changes.
In addition to this list of over 200 NOCs, the participation of National Paralympic Committees (NPCs) at the Paralympic Games requires standardised IOC codes, such as Macau (or as "Macau, China" since 1999) and the Faroe Islands, coded MAC and FRO respectively.
There are 206 current NOCs (National Olympic Committees) within the Olympic Movement. The following tables show the currently used code for each NOC and any different codes used in past Games, per the official reports from those Games. Some of the past code usage is further explained in the following sections. Codes used specifically for a Summer Games only or a Winter Games only, within the same year, are indicated by "S" and "W" respectively.

Two other significant code changes have occurred, both because of a change in the nation's designation as used by the IOC:
- HOL was changed to NED for the Netherlands for the 1992 Games, reflecting the change in designation from Holland.
- IRN was changed to IRI for Iran for the 1992 Games, reflecting the change in designation to Islamic Republic of Iran.
Special codes for Olympics
|ANZ||Australasia||1908–1912||Used in the IOC's medal database to identify the team from Australasia, composed of athletes from both Australia and New Zealand for the 1908 and 1912 Games. Both nations competed separately by 1920.|

|EUA|| United Team of Germany
from French Équipe unifiée d'Allemagne
|1956–1964||Used in the IOC's medal database to identify the United Team of Germany, composed of athletes representing the NOCs of both East Germany and West Germany for the 1956–1964 Games. The team was simply known as Germany in the official reports for those six games at the time.|
|EUN||Unified Team||1992||Used in 1992 (both Summer and Winter Games) for the Unified Team, composed of athletes from most of the ex-republics of the Soviet Union that chose to compete as a unified team.

The Netherlands Antilles Olympic Committee's membership from the IOC was withdrawn the previous year, and South Sudan has not formed an NOC. IOA was used again in 2016 for athletes from Kuwait as a result of the suspension of its National Olympic Committee.|
