When Is Mardi Gras 2025 Starting. The next mardi gras is tuesday, march 4, 2025. This is sort of a tricky question because of the sheer amount of festivities that revolve around the celebration.

Because mardi gras is always observed on the tuesday before ash wednesday, the date of observance changes each year but is typically held in either february or march. The barricades will be repositioned back onto the streets starting thursday, february 27 & 28, 2025.
