In diplomacy, an attaché is a person who is assigned ("attached") to the diplomatic or administrative staff of a higher placed person or another service or agency. Although a loan from French, in English the word is not modified according to gender.

An attaché is normally an official, under the authority of an ambassador or other head of a diplomatic mission, who serves either as a diplomat or as a member of the support staff. They monitor various issues related to areas of intervention. To this end, they may undertake the planning for decisions which will be taken and make all necessary arrangements, manage the agenda, conduct research for the study of particular matters, and act as representative when necessary.
