{{Main|List of Hey Arnold! characters}}
''Hey Arnold!'' features nine-year-old Arnold Shortman (voiced by [[Lane Toran]]; [[Phillip Van Dyke]]; Spencer Klein; and [[Alex D. Linz]]) and his neighborhood friends: Gerald Johanssen (voiced by [[Jamil Walker Smith]]), a street-smart character who generally serves as the leader of the group; and Helga Pataki ([[Francesca Marie Smith]]), a girl who bullies Arnold in order to hide the fact that she is in love with him. Bartlett drew inspiration from people he grew up with when creating the characters for the show.<ref name="How" />

Arnold lives with his eccentric but loving paternal grandparents, Phil Shortman ([[Dan Castellaneta]]) and Gertrude Shortman ([[Tress MacNeille]]), proprietors of the Sunset Arms [[boarding house]], in the fictional city of Hillwood. In each episode, he helps a schoolmate or boarding house tenant in solving a personal problem or encounters a predicament of his own. Many episodes involve [[urban legend]]s (usually told by Gerald), such as [[superhero]]es or the [[Headless Horseman]].

Other characters include students and faculty at P.S. 118, Arnold's school, and citizens of Hillwood. Certain episodes focus on the lives of supporting characters, such as the tenants of the boarding house that Arnold's grandparents own.
