Trois sondages relatifs à la saison 2018 de Division 1 FBS (Football Bowl Subdivision) de football américain universitaire sont reconnus par la NCAA même si de nombreux autres sondages sont publiés dans divers médias.
Contrairement à la plupart des autres sports, l'organe directeur de la NCAA ne décerne pas un titre de champion national au terme de la saison régulière. Ce titre est décerné par une ou plusieurs agences de sondages (les polls) ce qui explique que par le passé plusieurs équipes différentes pouvaient être déclarées championnes d'une même saison. Deux des principaux organismes de sondage, l'AP Poll et le Coaches'Poll, commencent à publier leurs classements avant le début de la saison et le font ensuite après chaque semaine de compétition.
Depuis la saison 2014, un classement est réalisé à partir de la mi-saison (après la semaine de compétition) : le College Football Playoff (CFP). La saison régulière est suivie d'un système de playoffs regroupant quatre équipes. Il remplace l'ancien système du . Après la dernière semaine de saison régulière, le comité du CFP dévoile le classement final de la Div. 1 du FBS. Ce classement détermine les quatre équipes qui participeront aux playoffs menant à la grande finale nationale du mois de . Il désigne également les équipes qui participeront aux 4 autres bowls majeurs n'accueillant pas les demi-finales du CFP.
