Russell Slade has been appointed the new Charlton manager on a three-year deal.
On Friday, Slade left his head of football role at Championship side Cardiff after just 28 days in the job and began talks with Charlton over the vacant managerial position at the Valley.
The 55-year-old had been Cardiff boss for the past two seasons before a management reshuffle saw Paul Trollope assume first-team coaching duties and Slade move upstairs.
But Slade has decided to return to the dugout, signing a contract that will keep him at the League One club until 2019.
"I am very pleased to be appointed manager of Charlton, a club with a fantastic tradition and history," Slade told the club's official website.
"I was attracted to Charlton as it has has great facilities, passionate fans and a very successful academy. This is a hugely exciting opportunity and I cannot wait to get started."
Charlton chief executive Katrien Meire added: "We're delighted to have agreed terms with Russell.
"We don't underestimate the challenge of getting Charlton back into the Championship. We believe Russell is the man to help us achieve this and, with the help of everyone involved in the club, ensure that Charlton have a successful 2016/17 campaign.
"Russell has vast experience in the division and is a two-time League One Manager of The Year. He joins us as Manager on a long-term contract and his appointment represents the start of an exciting new era at the club under his guidance."
After four successful years in charge of Leyton Orient, Slade was appointed as manager at Cardiff following the sacking of former Manchester United striker Ole Gunnar Solskjaer in 2014.
The former Brighton and Yeovil boss was given the task of gaining Cardiff promotion back to the Premier League but could only guide the Bluebirds to 11th and eighth-placed finishes during his two years in charge.
Charlton have been searching for a new boss since Jose Riga announced his resignation following their final game of the season, with the Addicks already relegated to League One.
They failed with an approach for the then Northampton Town boss Chris Wilder, who subsequently joined Sheffield United, before securing the services of Slade.
