Living room (or sitting room, especially in commonwealth English, also called lounge room in Australia or lounge in the UK) is a room for entertaining guests, reading, watching TV or other activities.

In modern homes and apartments the living room has replaced the old fashioned parlour. The term marks the twentieth-century effort of architects and builders to strip the parlour of its burial and mourning associations. Typically, a living room will be furnished with a sofa, chairs, occasional tables, perhaps a television and/or stereo equipment, bookshelves, as well as other pieces of furniture. Traditionally a sitting room in the United Kingdom would have a fireplace that burns log, although now many have been converted to use gas (and have imitation log) in more recent years.

In many homes, the living room is reserved for more formal and quiet entertaining while a separate recreation room or family room is used for more casual activities.

The term front room can also used to describe a living room, because in many homes the front door opens into the living room.
