Recurring characters

This is the list of recurring characters on 24 who appeared (or were heard) live in two or more episodes of a season.

The total number of each character's appearances is included per season, regardless of whatever credits the actor may have received or if the actor or body double was uncredited. Characters who have appeared in multiple seasons have their grand total calculated in the final section. As with the appearances templates on each character's page, non-live audio, prerecorded footage, and photographs are excluded.
