Ettumanoor Mahadeva temple is an ancient Shiva temple in Kottayam, Kerala, India. It has brought glory and fame to the place. Myths have it that the Pandavas and the sage Vyasa had worshipped at this temple. The name of the place has its origin from the word 'manoor', which means the land of deer. The temple is one of the major Shiva temples in Kerala counted along with the Shiva temples of Chengannur Mahadeva Temple, Kaduthruthy Mahadeva Temple, Vaikom Temple, Ernakulam Shiva Temple and Vadakkunathan temple.

Legend is that the Shiva lingam found here was installed by the Demon KHARA from the epic Ramayana. He worshipped Shiva at Chidambaram and obtained 3 Lingams. He carried one in each hand and the third in his mouth. Since this Lingam was installed from his mouth, the place got the name “Kadichiruthy Prathishitta”. (Kadichu – bite, thuruthy – to be placed). The other 2 Lingams were installed at Vaikom & Ettumanoor. Hence it is believed that darshan of all 3 Lingams before noon on a single day fulfils ones wishes. Distance from Malliyoor Mahaganapathy temple to Kaduthuruthy Mahadeva Temple is 5 kms.
