Elsa Castillo Rada (19 October 1963) is a Venezuelan teacher and trade unionist, member of the National Trade Union Alliance (Alianza Nacional Sindical).
Castillo was one of the leaders of the call for the march of teachers and workers on 23 January 2023. The same month, a trend was denounced with the intention of delegitimizing the call for protests by educators in the country generated by a group of pro-government digital communicators, related to the National Organization of Alternative Communicators, accusing Castillo of traveling in a "private jet".
