Scarborough Salvation Army and Westway Open Arms in Eastfield are among two food banks in the county to have benefited from the scheme.
This involved filling boxes every day with collected items and delivering them to organisations helping the most vulnerable.
Chief Constable Lisa Winward said: “There are so many wonderful charities, groups and organisations across North Yorkshire who are doing magnificent work locally to help people in our communities who need it. And, so this was a perfect opportunity for us, the police, to show our support and help individuals and families in their time of need, especially at Christmas time.
“My thanks go to our officers, staff and volunteers across the force who have kindly donated or given up their time to support the reverse advent calendar in some way and make it the success it has been. I was really overwhelmed by their fantastic efforts.”
Over 55 boxes and six shopping trolleys of donations have been delivered to charities across the county.
