What was the name of Kevin Arnold's best friend on The Wonder Years?

Kevin Arnold's best friend on The Wonder Years was Paul Pfeiffer. Played by Josh Saviano, Paul was Kevin's longtime friend, neighbor, and frequent companion during the show's stories about growing up in suburban America.

Paul was written as bright, academically successful, and notably prone to allergies. His friendship with Kevin was central to the series, although it sometimes became strained as Kevin grew older, made new friends, and became increasingly focused on Winnie Cooper. Paul also attended a private preparatory school for one season, creating additional distance between the two boys.

A common mix-up is confusing Paul with Wayne Arnold, Kevin's older brother, or Winnie Cooper, Kevin's close friend and romantic interest. Paul is the character most consistently identified as Kevin's best friend, and the role was performed by Josh Saviano throughout the original 1988–1993 series.
