David Moyes expressed his delight at returning to Everton as manager after being appointed for a second stint.
The 61-year-old Scot has signed a two-and-a-half-year contract with the club, following the dismissal of Sean Dyche on Thursday.
Everton currently sit 16th in the Premier League, just one point above the relegation zone, with only three wins from 19 matches this season.
“I enjoyed 11 wonderful and successful years at Everton and didn’t hesitate when I was offered the opportunity to rejoin this great club,” said Moyes.
“Now we need Goodison and all Evertonians to play their part in getting behind the players in this important season so we can move into our fabulous new stadium as a Premier League team.”
Moyes previously managed Everton from 2002 to 2013 before taking charge of Manchester United, Real Sociedad, Sunderland, and West Ham on two occasions.
The 61-year-old has been out of work since departing West Ham at the end of last season, where he capped his tenure by leading the club to victory in the Europa Conference League in 2023.
From relegation fight to Champions League – the first Everton spell
Moyes spent 11 years at Everton before leaving to take charge of United as Sir Alex Ferguson’s successor in the summer of 2013.
Following a four-year spell at Preston, he joined Everton in March 2002, with the Toffees in danger of relegation.
Moyes won his first match and went on to take charge of more than 500 games.
Everton reached the FA Cup final in 2009 and finished in the top eight of the Premier League nine times, including fourth in 2004-05, which took them into Champions League qualifying.
Moyes gave Wayne Rooney his professional debut and signed several players who would become Everton greats, including Tim Cahill and Marouane Fellaini.
