The Premier League club’s show of support arrives in the form of a friendly match.
The high profile game on Wednesday March 21 will be sure to see many of the Hammers’ big name players turn out - with money going towards the National League club.
A West Ham statement confirmed they are backing the club next month.
West Ham United Chairman David Sullivan said: “As soon as we heard that Dagenham & Redbridge were in need of financial assistance, David Moyes and I didn’t hesitate to offer our help by sending down a team for a fundraising friendly with our neighbours.
“We’ve always enjoyed a close relationship with the Daggers and are looking forward to this match, not only as a means of raising important funds, but also because it will be an enjoyable evening of football.”
Dagenham & Redbridge chairman Paul Gwinn said: “A massive thank you goes to West Ham United for agreeing to the match on 21 March.
“The support we’ve received from David Sullivan and David Moyes is hugely appreciated. It really will help save our club and I couldn't have asked for more.”
