Duff Muttu is a traditional folk dance form that originated in the Malabar region of Kerala, India. It is typically performed during Islamic festivals, especially during the Muharram festival. The dance form involves a group of performers, usually men, who dance to the beats of a traditional drum called the 'duff'.

The dancers wear colorful costumes and carry swords or sticks while performing intricate dance movements. The performance is accompanied by singing and chanting of Islamic religious verses. The dance is believed to have originated as a form of mourning for the martyrdom of Prophet Muhammad's grandson, Imam Hussain.

Today, Duff Muttu has become a popular cultural form that is performed not only during religious festivals but also at weddings and other celebrations. The dance has undergone several changes over the years, with new movements and music being added to it. However, it still retains its traditional charm and remains an important part of Kerala's cultural heritage.
