Former Test batsman Langer, 47, will take charge of all three formats beginning on May 22.
His first games in charge will be five one-dayers in England this summer.
He will also sit on the panel drafting a charter of behaviour for the Aussie team after years of sledging and abusing opponents culminated with the ball-tampering against South Africa in March.
With captain Steve Smith and batsmen David Warner and Cameron Bancroft all banned, Langer will work with new skipper Tim Paine and fast bowler Pat Cummins, who is expected to be named vice-captain.
Langer was endorsed as Lehmann's replacement by the Cricket Australia board on Wednesday night.
Chief executive James Sutherland said: "Justin was the clear standout, particularly based on his recent coaching and player development achievements.
"Justin's work ethic, leadership and values are among his strongest attributes, and he is widely respected across the global cricket community."

Langer referred indirectly to the ball-tampering episode which has rocked the sport in Australia.
He said: "There will be some significant challenges ahead for our group, but there is a wealth of talent in Australian cricket that I know will do us all proud.
"I'm thoroughly looking forward to working with all players, as we strive for a successful men's team across all formats, with the support and respect of the Australian public."
Langer had previously been linked to the vacant England coaching position before another Australian, Trevor Bayliss, was appointed in 2015.
Before taking up coaching in Western Australia, Langer spent time as a specialist batting coach with the national team under former teammate Ricky Ponting's captaincy.
