Opened canned potatoes last 3–4 days in the fridge. Unopened, they keep 2–5 years in the pantry.
USDA FoodKeeper lists canned potatoes under “Canned goods (low acid such as meat, poultry, fish, gravy, stew, soups, beans, carrots, corn, pasta, peas, potatoes, spinach)”, so this page uses that entry's storage times.

- Canned items will be safe to eat well past the ‘use-by’ or ‘best by’ date as long as the can shows no dents, rust, or swelling.
- Refrigerate after opening unless the label says otherwise.
- Use a clean utensil each time; crumbs and double-dipping shorten shelf life.
- Wipe the rim and close the lid tightly.
