A marmite is a traditional crockery casserole vessel found in France. It is famed for its "pot-belly" shape.

According to the French culinary reference work [[Le Répertoire de la Cuisine]], a marmite can be either a stock pot or "a French pot with lid similar to a casserole with two finger-grips on each side."

It lends its name to Marmite, a British savoury spread and to [[marmitako]], a Basque tuna dish.
