A conference hall, conference room, or meeting room is a room provided for singular events such as business conferences and meetings.

Room

It is commonly found at large hotels and convention centers though many other establishments, including even hospitals,^[1] have one. Sometimes other rooms are modified for large conferences such as arenas or concert halls. Aircraft have been fitted out with conference rooms.^[2] Conference rooms can be windowless for security purposes. An example of one such room is in the Pentagon, known as the Tank.^{[citation needed]}

Typically, the facility provides furniture, overhead projectors, stage lighting, and sound system.^[3]

Smoking is normally prohibited in conference halls, even when other parts of buildings permit smoking.^[4]

Sometimes the term 'conference hall' is used synonymously with 'conference center' as, for example, in 'Bandaranaike Memorial International Conference Hall'.

Some meeting rooms come equipped with booking management software, depending on the needs of the company that owns them.

Typically, a medium to large office or post-secondary educational facility has smaller meeting rooms, often called a conference room or a huddle room.
