BBC Wales Sport understands Arsenal legend Thierry Henry, Georgia boss Willy Sagnol and surprise contender Des Buckingham, the Oxford United boss, were all spoken to about the post, but Bellamy was the Football Association of Wales (FAW’s) first choice.
The FAW’s chief football officer, Dr David Adams, said: “We undertook a thorough recruitment process for the new men’s national team head coach and Craig was identified as the standout candidate.
“We are all looking forward to the Nations League games and working with Craig to deliver success for Welsh football.”
Bellamy, who narrowly missed out to Ryan Giggs for the job in 2018, is said to have impressed during discussions – and will now get the chance to lead the side in qualification for the 2026 World Cup.
His first game as Wales manager will be a Nations League home tie against Turkey on 6 September, followed by a trip to Montenegro on 9 September.
Bellamy retired from international football in 2013, missing out on the chance to play in a major finals as Wales qualified for Euro 2016 under Chris Coleman.
He took his first steps in coaching with Cardiff City’s academy before serving as assistant manager to former Manchester City team-mate Vincent Kompany at Anderlecht and then Burnley.
Bellamy stood in when Kompany served a touchline ban last season and stepped up when the Belgian left for Bayern Munich in May.
But with Burnley opting for former Fulham and Bournemouth manager Parker for their permanent role, it opened the door for the FAW.
Bellamy now returns to Wales, having ended his playing career with hometown club Cardiff City, helping them win promotion to the Premier League in 2014.
