A marquee is a large tent used for hosting events. They are often used for big parties like weddings, for festivals, or for shows. A marquee is a temporary building. It can be put up for a few days or weeks and then taken down.

Marquees have a frame made of long poles. These poles are usually made of metal, like steel or aluminum. The roof and walls are made of a strong fabric. This can be canvas or a type of plastic called PVC. The marquee is held down with ropes and pegs (stakes) that go into the ground.
There are two main types of marquee.
A pole marquee has poles in the middle of the tent to hold up the roof. This is a traditional type of marquee.
A frame marquee has a strong metal frame that holds up the roof. It does not need poles in the middle. This means there is more open space inside.

In North America, the word marquee can also mean something else. It is a sign over the entrance of a theater, cinema, or hotel. This sign has lights and shows the name of company, a play, movie, or performer.
