Elite sport has been suspended worldwide in a bid to slow the spread of the virus.
There are over 56,000 confirmed cases in Spain, with more than 4,000 deaths, but Madrid are aiding the response.
The 13-time European champions are working with the country's National Sports Council to "supply and distribute strategic medical supplies", a statement read.
The 81,000-seater Bernabeu will provide a space to store donated medical supplies, while Madrid are facilitating donations to the Ministry of Health.
"All of the stored supplies will be passed on to the Spanish health authorities, under the authority of the Spanish government, so that the resources, so necessary in the current health emergency situation, are employed in the best and most efficient manner," Madrid said.
