A wedding mandap (विवाह मंडप, लग्नमण्डप) is a mandap (covered structure with pillars) temporarily erected for the purpose of a Hindu or Jain wedding. The main wedding ceremonies take place under the mandap.

It is traditionally made of wood, although now modern materials are sometimes used. It often comes as a set that includes pillars supporting a frame, royal chairs for the bride and the groom, side chairs for parents and a pedestal for the sacred fire.
