A wagon fort, wagon fortress, wagenburg or corral, often referred to as circling the wagons, is a temporary fortification made of wagons arranged into a rectangle, circle, or other shape and possibly joined with each other to produce an improvised military camp. It is also known as a laager, especially in historical African contexts, and a tabor among the Cossacks.

A wagon or waggon is a heavy four-wheeled vehicle pulled by draught animals or on occasion by humans, used for transporting goods, commodities, agricultural materials, supplies and sometimes people.
