Lingaraja Temple (Odia: [liŋɡɔraːd͡ʒɔ] ) is a Hindu temple dedicated to Shiva and is one of the oldest temples in Bhubaneswar, the capital of the Indian state of Odisha, India. The temple is the most prominent landmark of Bhubaneswar city and one of the major tourist attractions of the state. Shiva's consort and the temple's presiding Goddess, Parvati, is referred to as Annapurna or Girija.

The Lingaraja temple is the largest temple in Bhubaneswar. The central tower of the temple is 180 ft (55 m) tall. The temple represents the quintessence of the Kalinga architecture and culminating the medieval stages of the architectural tradition at Bhubaneswar. The temple is believed to be built by the kings from the Somavamsi dynasty, with later additions from the Ganga rulers. The temple is built in the Deula style that has four components namely, vimana (structure containing the sanctum), jagamohana (assembly hall), natamandira (festival hall) and bhoga-mandapa (hall of offerings), each increasing in the height to its predecessor. The temple complex has 108 other shrines and is enclosed by a large compound wall.

Bhubaneswar is called the Ekamra Kshetra as the deity of Lingaraja was originally under a mango tree (Ekamra) as noted in Ekamra Purana, a 13th-century Sanskrit treatise. The temple is active in worship practices, unlike most other temples in Bhubaneswar. The temple has images of Vishnu, possibly because of the rising prominence of Jagannath sect emanating from the Ganga rulers who built the Jagannath Temple in Puri in the 12th century. The central deity of the temple, Lingaraja, is worshipped as Shiva.

Lingaraja temple is maintained by the Temple Trust Board and the Archaeological Survey of India (ASI). The temple has an average of 6,000 visitors per day and receives hundreds of thousands of visitors during festivals. Shivaratri festival is the major festival celebrated in the temple and event during 2012 witnessed 200,000 visitors. The temple compound is not open to non-Hindus, but there is a viewing platform beside the wall offering a good view of the main exteriors. This was originally erected for a visit by Lord Curzon, the then Viceroy.
