Group captain is a senior commissioned rank in many air forces. Group captain has a NATO rank code of OF-5, meaning that it ranks above wing commander, immediately below air commodore and is the equivalent of the naval rank of captain and the rank of colonel in other services.

While the rank originated in the British Royal Air Force (RAF), group captain is a rank used by the air forces of many Commonwealth and other countries that have been influenced by British military culture. It is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure.
It is usually abbreviated Gp Capt. In some air forces (such as the RAF, IAF and PAF), GPCAPT is used while in others (such as the RAAF and RNZAF) and sometimes, especially in historical contexts, as G/C. The rank of group captain is always the full phrase; it is never abbreviated as "captain".
