A samosa is a fried or baked dish with a savoury filling, such as spiced potatoes, onions, peas, or lentils. Its size and consistency may vary, but typically it is distinctly triangular or tetrahedral in shape. Indian samosas are usually vegetarian, and often accompanied by a mint chutney.

Samosas are a popular entrée, appetizer, or snack in the local cuisines of the Arabian Peninsula, Southeast Asia, Southwest Asia, the Mediterranean, the Indian subcontinent, the Horn of Africa, East Africa, North Africa, and South Africa. Due to cultural diffusion and emigration from these areas, samosas in today's world are also prepared in other regions.
