A green room is a space in a performing venue which is set aside for performers to lounge in when they are not required on stage. It is typically set apart from the stage and the audience, so that the actors can hold conversations and play games without being heard by the audience. A green room is usually equipped with couches and chairs, reading materials, and games, and is a popular place to unwind after the show as well.
Unlike dressing rooms, another popular lounging area, the green room is not equipped for preparations to go on stage, and is designed as a purely recreational area. It also not usually established with the intent of being a peaceful and quiet space; the green room is an area for socializing. Actors who need quiet before going on stage usually find other areas of the theater in which to focus.
