Padalathri Narasimhar Temple or Narasimhar Temple (also called Singaperumal Koil) is dedicated to Hindu god Vishnu (Narasimha) located in Singaperumal Koil, near Chennai City, in the South Indian state of Tamil Nadu.

Constructed as rock-cut architecture, dedicated to Vishnu, who is worshipped as Narasimhar, and his consort Lakshmi as Ahobilavalli, the temple was built by the Pallavas during the 8th century.

The temple is maintained and administered by the Hindu Religious and Endowment Board of the Government of Tamil Nadu.

Hiranyakashipu was troubling the devas and devis as he got a boon from Brahma, that neither human nor an animal could kill him.

His anger was not quenched even after slaying the asura king, but Prahlada sang and prayed Narasimha to calm down, which he acceded to.

The oldest inscription is found from the period of Raja Raja Chola (985-1014 CE), the most famous Chola emperor from Thanjavur in 990 CE indicating a gift of 26 sheep for producing ghee for the perpetual lighting of the temple by oil lamps.

As at other Vishnu temples of Tamil Nadu, the priests belong to the Brahmana Varna of the Vaishnavaite community.

The temple rituals are performed four times a day: Ushathkalam at 8 a.m., Kalasanthi at 10:00 a.m., Sayarakshai at 5:00 p.m. and Ardha Jamam at 8:00 p.m. Each ritual has three steps: alangaram (decoration), neivethanam (food offering) and deepa aradanai (waving of lamps) for both Narasimhar and his consort Ahobilavalli.

During Aani Brahmotsavam, the temple car housing the festival deities of Narasimhar and Ahobilavalli is drawn around the streets of Singaperumalkoil.

The temple is maintained and administered by the Hindu Religious and Endowment Board of the Government of Tamil Nadu.
