Coleman makes the move to Wearside on a two-and-a-half-year deal after turning down the offer of several new contracts with Wales.
The 47-year-old enjoyed a fruitful spell with his national side, guiding them into the top ten of FIFA's world rankings and leading them to the semi-finals of Euro 2016.
Despite plenty of interest, Coleman has now chosen Wearside as the latest step in his managerial career and took his first training session on Sunday morning ahead of Sunderland's Championship clash with Aston Villa in midweek.
Coleman faces a tough task to impress the Sunderland faithful, with the club currently four points adrift of safety in 24th position in the Championship table.
Speaking to 'safc.com', the former Fulham boss expressed his delight at being named Sunderland's new boss, saying: “It’s an honour to be appointed the manager of Sunderland AFC and I’m over the moon that the club believes I am the right man.
“The club worked incredibly hard to make sure we were a good fit and to show me the potential that can be achieved here.
“I believe that every person at this football club, every player and every supporter has a part to play in getting us back to where we belong.”
The club's chief executive Martin Bain was equally as thrilled with the appointment, telling their official website: “The football club has conducted a thorough process over the last three weeks to identify the best manager for the job, before and after which Chris was the clear first choice.
“We are delighted that he and Kit Symons, his assistant manager, have joined us, and are now focused on working together to get the football club moving in the right direction.”
