Ross' appointment was announced on Thursday, a day after news of the hire initially broke. He has agreed to a three-year contract with an option for a fourth.
The 42-year-old is only a few years removed from his playing days, having retired after helping the Cubs win the World Series for the first time since 1908 in 2016, and has worked primarily as a broadcaster since then.
He played for eight teams during his 14-year playing career, serving mostly as a backup catcher.
Ross worked as an analyst for ESPN since retiring while also operating as a special assistant to the Cubs' front office.
"David is as gifted a leader as I've ever come across, and I expect him to become a great manager," Cubs president of baseball operations Theo Epstein said in a release.
"He is a natural connector with a high baseball IQ and a passion for winning. David has always stood out for his ability to cultivate the ingredients of a winning culture — accountability, hard work, hustle, competitiveness, trust, togetherness and team identity."
