Fishing in Montana requires a valid state fishing license for anglers. Licenses include resident and non-resident, annual and short-term, purchasable online or at license vendors statewide.
In Montana, no fishing license is required for anglers under 12. Residents 62 and older qualify for a discounted license. A few other exceptions worth knowing:
Free fishing days — most states designate 1–2 weekends a year where anyone can fish without a license
Tribal waters — tribal members fishing on tribal land operate under separate tribal regulations
Private ponds — landowners fishing their own water typically don't need a license
Non-residents usually pay more for a license than residents. Some species also require an extra stamp or endorsement on top of your base license.
