The Hammers legend retired from football at the end of last season but will return to the Premier League club in a new role that will begin in January.
Noble said: "I’m really happy to be coming back and can’t wait to get started. I’d like to thank the club for giving me the opportunity – it’s a great honour for me to take up this role at West Ham United.
"I’ve spent the last 24 years as a player here, first in the academy and then in the first team, and obviously have a deep knowledge and understanding of the club. Throughout my playing career, the one thing I strived for more than anything was constant improvement, on and off the pitch.
"That became even more important to me when I was named club captain in 2015 and the last seven years have given me such great experience and preparation for the next stage of my life and career."
He added: "In particular, the last two years, as my playing days began to naturally wind down, gave me a fantastic opportunity to really spend some time educating myself and gaining greater knowledge and understanding of the work that goes on behind the scenes. This club has made some fantastic strides forward in that period and I am really looking forward to coming back at such an exciting time."
Noble will work closely with Hammers manager David Moyes in the role and the coach is looking forward to the new arrangement.
He said: "I am really pleased to welcome Mark back and to have the opportunity to work closely with him again. He was a great asset and strength to me as a player and a captain, and I know he will give the club and myself fantastic support again in this role."
