Toews (20 years, 79 days) joins Pittsburgh Penguins center Sidney Crosby and Tampa Bay Lightning center Vincent Lecavalier among the youngest players to captain their respective clubs. Crosby took over at 19 years and 297 days and Lecavalier at 19 years and 330 days.
"Jonathan deserves this honor, he is a tremendous individual and a wonderful leader on and off the ice," Blackhawks GM Dale Tallon said. "He has experience in captaining teams from his World Junior appearances and guys follow his lead in our locker room."
Toews had 24 goals and 54 points as a rookie last season.
