Deoghar is the headquarters city of Deoghar District in the Santhal Parganas division of the state of Jharkhand.
It is an important Hindu pilgrimage centre, having in Baidyanath Temple one of the twelve Shiva Jyothirlingams in India and also one of the 51 Shakti Peethas in India.
The climate is dry and congenial and Deoghar is still considered a health resort in spite of the great congestion particularly due to the temple of Vaidyanath.
