Language is not only the basis of our communication, but also our thoughts. That is why, in the academic world, it is necessary to incorporate the use of non-sexist language, in order, almost unconsciously and collectively, to educate in equality. In this sense, museums, which have yet to achieve real integration in terms of their contents, must also be concerned about the language with which they promote their collections, activities, etc. In this text, the use of non-sexist language in the Spanish-speaking museum field will be reviewed, taking as examples some of the most prominent museums in different countries. To do this, a review of their media (web page, social networks, educational materials, etc.) will be made and the results of a survey made to these museums will be presented to know their opinion on this issue. In addition, some recommendations in this regard will be proposed.
