Карпообразные внешне напоминают Сельдеобразных, отличаясь наличием веберова аппарата, образованного четырьмя передними позвонками. Их тело покрыто циклоидной чешуей или голое, голова голая. Это рыбы, у которых челюсти не несут зубов, однако у них имеются сильные зубы на нижних глоточных костях жаберного аппарата, образующие глоточный жевательный аппарат. Жирового плавника нет, рот более или менее выдвижной и нередко снабжен усиками; плавательный пузырь подразделен на два или больше отделов.
