A wet market is a marketplace selling fresh foods such as meat, fish, produce and other consumption-oriented perishable goods in a non-supermarket setting, as distinguished from "dry markets" that sell durable goods such as fabrics, kitchenwares and electronics. These include a wide variety of markets, such as farmers' markets, fish markets, and wildlife markets. Not all wet markets sell live animals, but the term wet market is sometimes used to signify a live animal market in which vendors slaughter animals upon customer purchase, such as is done with poultry in Hong Kong. Wet markets are common in many parts of the world, notably in China, Southeast Asia, and South Asia. They often play critical roles in urban food security due to factors of pricing, freshness of food, social interaction, and local cultures.

A marketplace, market place or just market is a location where people regularly gather for the purchase and sale of provisions, livestock, and other goods. In different parts of the world, a marketplace may be described as a souk, bazaar, a fixed mercado (Spanish), or itinerant tianguis (Mexico), or palengke (Philippines). Some markets operate daily and are said to be permanent markets while others are held once a week or on less frequent specified days such as festival days and are said to be periodic markets. The form that a market adopts depends on its locality's population, culture, ambient and geographic conditions. The term market covers many types of trading, as market squares, market halls and food halls, and their different varieties. Thus marketplaces can be both outdoors and indoors, and in the modern world, online marketplaces.
