Salon tango (also referred to as Salon-style tango or tango de salon) is tango as it is danced at milongas - social tango-dance events. It comes in a variety of sub-styles which evolve in conjunction with social and geographic settings in its history and the present. There are certain traits which differentiate it from other forms of tango, like International-style ballroom tango, American tango, performance tango (fantasia), and others.​
