This is to meet increased demand due to the coronavirus pandemic that has caused a worldwide catastrophe.
The clubs are donating £50,000 each to The Trussell Trust.
Here are further details regarding the donations made by the two sides.
Local food banks can compensate for temporary loss
Local food banks can now increase capacity and compensate for the temporary loss of food donations on matchdays through the MCFC Fans Foodbank Support and MUFC Fans Foodbank.
These groups generally collect supplies outside Old Trafford and The Etihad before home matches.
However, this has been interrupted by the suspension of football due to the coronavirus pandemic.
'We are pleased to come together with our fans'
In a joint statement, the two clubs said: "We are proud of the role our supporters play in helping local food banks and recognize the increased strain likely to be placed on these charities by the impact of coronavirus."
"At a time of challenge, we are pleased to come together with our fans to help vulnerable members of society in a City United."
Key details about the Trussell Trust
The Trussell Trust support is a network of over 1,200 food bank centres, including 19 in the Greater Manchester area. These centres will be the beneficiaries of this donation.
"As the coronavirus pandemic develops, more people than ever may need help from food banks across our network," said Rachel Macklin, operations manager at Trussell Trust.
Two clubs making this contribution will make a huge difference
A spokesperson for the Manchester United Supporters Trust told Sky, "The news that Manchester United and Manchester City have agreed to make such a large contribution is fantastic news and will make a huge difference supporting vulnerable people in communities across Manchester at this time."
