The Duluth Cash Spiel is an annual bonspiel, or curling tournament that is part of the Ontario Curling Tour.
The men's event was held from at least 2001 to 2016 as part of the men's World Curling Tour and was known as the Coors Light Cash Spiel from 2010, while the women's event was held from 2004 to 2016 and was known as the Molson Cash Spiel from 2010.
Both events had been previously known as the Labatt Cash Spiel.
The men's event was brought back in January 2024 under the new Duluth Cash Spiel name, while the women's event returned in December 2024.
The event takes place at the Duluth Curling Club in Duluth, Minnesota.
