Former Everton, Manchester United and Sunderland boss, David Moyes has been handed an initial six-month deal, taking him through until the end of the season, after replacing Slaven Bilic who was sacked on Monday.
Croatian boss Bilic oversaw a difficult start to the campaign, managing just two wins from 11 Premier League matches before leaving with the club in the relegation zone.
The Scot’s task is to establish the Hammers in mid-table. He is expected to appoint former England international Stuart Pearce as part of his coaching staff.
Alan Irvine and Chris Woods, who is already at the London Stadium as a goalkeeping coach, will also be part of the 54-year-old’s team.
Moyes is expected to take training for the first time on Tuesday and his first match will be at Watford on November 19.
In his unveiling video on West Ham’s Twitter account, Moyes attempted to rally the fans, saying: ‘I’m really looking forward to meeting the supporters, being in the stadium with them.
‘I’m looking forward to seeing them getting right behind the team and my team also. We need the support, we need everyone with us.
‘It’s a big job we have in hand now but I’m sure with everybody together we can get the right results between now and the end of the season.’
In an interview with West Ham’s website, Moyes added: ‘It feels great to be here. West Ham is a big club. Wherever you go they are known.
‘I’ve been really fortunate in that I’ve managed some really great clubs, and I have been offered some other opportunities recently.
‘But I wanted a job that would give me a real good chance. I wanted a big fanbase, a big club, and West Ham fitted the bill.
‘I’m really just looking forward to getting started, because we are now in the season and we have to get up-and-running right away to get the job done.
‘We are without some players at the moment who are away on international duty but we will get the chance to work with the players who are here this week and I am looking forward to it.’
