Deoghar is a Hindi word and the literal meaning of 'Deoghar' is abode ('ghar') of the Gods and Goddesses ('dev').

Deoghar is also known as "Baidyanath Dham", "Baba Dham” . Deoghar". The origin of Baidyanathdham is lost in antiquity. It has been referred to as Haritakivan or Ketakivan in Sanskrit Texts. The name Deoghar seems to be of recent origin and probably dates from the erection of the great temple of Lord Baidyanath.

Deoghar is a famous health resort and a major Hindu pilgrimage center. Baidyanath Temple in Deoghar holds one of the twelve 'Shiva Jyothirlingams' and is also one of the 51 saktipeeths in India. The ‘Purans’ refer to this temple as fit place for funeral obsequies. It is also famous for the mela of Shrawan (5th month according to the Hindu calendar system). It is the only place in India where the jyotirlinga and the saktipeeth are together.
