Tens of thousands of pounds of food, groceries and clothing were given away to Nassau County residents in need.
The international relief organization partnered with local churches and business owners to host the event at the Mitchel Field Athletic Complex in Uniondale.
It's being billed as the largest single day combined humanitarian effort Long Island has ever seen.
Helping to sponsor the event was Bob Jesberger, the owner of Mid-Island Collision.
"This is a community of the haves and the have-nots," said Jesberger.
"And the haves need to do a lot more than what they're doing."
"We've seen a great influx of people just really in need," said Gabrielle Rizzuto, the project coordinator for the event.
"We've given away already about 500 pairs of shoes, and we have 5,000 bags of groceries that are halfway gone."
There were also free health screenings so the many uninsured Long Islanders could get a checkup.
Convoy of Hope partnered with about 40 local churches to help local needy families.
