Maria, the first Category 4 hurricane to make landfall on Puerto Rico since 1932, devastated the island on Wednesday, knocking out electricity and soaking towns.
Donors can give to a campaign or directly to GoFundMe, which will then distribute the money to the campaigns.
This initiative, from Beatriz Rosselló, the first lady of Puerto Rico, enlists private sector help in providing aid to those affected by Hurricanes Irma and Maria.
Donations to the faith-based group will help to provide shelter, water, tarps, tents, kitchen kits and other supplies to families affected by the storm, it said.
The group has been working with local authorities to provide emergency care after Hurricane Irma and said it had moved medical supplies into place ahead of Hurricane Maria.
