Chir batti (ghost-light), also spelled chhir batti or cheer batti, is a strange dancing light phenomenon occurring on dark nights reported from the Banni grasslands, its seasonal marshy wetlands and the adjoining desert of the marshy salt flats of the Rann of Kutch near Indo-Pakistani border in Kutch district, Gujarat State, India. Local villagers have been seeing these sometimes hovering, sometimes flying balls of lights since time immemorial and call it Chir Batti in their Kutchhi–Sindhi language, with Chir meaning ghost and Batti meaning light.
