The National Delegation of the Youth Front (Spanish: Delegación Nacional del Frente de Juventudes) was a political-administrative body created in Spain in 1940, as an autonomous youth section of FET y de las JONS, the only authorized political party for the dictatorship of General Franco (1936–1975).

The aims of the Youth Front are clearly stated in its Foundational Law, and were addressed to the entire Spanish youth, both those affiliated voluntarily, and, here lies the singularity of the Front and its influence on Spanish society at the time, the unaffiliated, who received the denomination of "framed" and were divided into "schoolchildren" (of all educational levels), "apprentices" (workers), and "rural" (peasants).

For affiliated youth, the purposes were the following (Article 7 of the Law):a) Political education, in the spirit and doctrine of the Movement.b) Physical and sports education.c) Pre-military education.d) Initiation to the Home female youth.e) Collaborate in the cultural, moral and social formation with the institutions to which they belong and provide religious education proper to the Church.f) Organize and direct camps, colonies, shelters, courses, academies and any other work of this kind, directed to the fulfillment of its functions.g) Complete, with respect to its affiliates, the work of the State, mainly in matters of health, education and work.

The founding law pointed to the existence of a physical education advisor and another of religion, whose first holders were Lieutenant General Joaquín Agulla and Jiménez-Coronado, and the Patriarch Leopoldo Eijo y Garay, respectively.

One of the means employed was the so-called "Teaching Evenings", time that the companies gave to the Youth Front so that the apprentices could attend the activities and classes that the organization taught.

The services and activities developed by the Youth Front were very broad and numerous, covering, in addition to the educational field, free time, culture and even information.

In the free time highlights were mainly tournaments and competitions of sports activities, camps and hostels, cultural and leisure activities such as theater, model airplanes, school health and companies such as BCB (Blue Chain of Broadcasting), the Travel Office TEET (Tourism, Exchange and Educational Trips), the Spanish Network of Youth Hostels, the Youth Bazaar Network, and the Editorial Doncel, through which he edited comics as Balalín (1957-1959) and Trinca (1970-1973).
