The Assembly of First Nations National Youth Council (AFN-NYC) is a key component of the AFN, representing First Nations youth across the country and advocating for issues that impact them on a daily basis. The AFN-NYC creates and promotes opportunities for youth to engage in important issues such as languages, life promotion, healthy lifestyles, climate action, culture and education. The AFN-NYC reports to the AFN as an advisory body on all issues from a youth perspective.

The AFN-NYC operates as a 20 member council of First Nations youth from each of the 10 AFN regions. Each region appoints one male and one female representative, whose length of term depends on their regional process. The representatives are selected by regional youth councils or by their Regional Chief. The two current co-chairs of the AFN-NYC are Hailey Rose and Rosalie LaBillois.
