Atcheeswarar Temple, Hindu temple in Achirupakkam, Tamil Nadu, India

Atcheeswarar Temple is a Hindu temple in Acharapakkam, Kanchipuram district, Tamil Nadu, covering about 1.21 acres. It has a five-tiered raja gopuram and a tank in front. The sanctum of Aksheeswaraswamy is set axial to the flagstaff and gopuram, and the west-facing shrine of his consort Sundaranayagi is in the first precinct, along with images of Saraswati, Lakshmi, Saptamatrika and Ayyappa.

The temple is believed to be between 1000 and 2000 years old and was recognized in devotional hymns by Saint Tirugnanasambandar as the 29th sacred site in the Thondai region. That recognition helped place it among the established Hindu pilgrimage sites of Tamil Nadu.

Each year in April and May, the Chithirai Brahmmotsavam festival draws devotees from across the region for several days of rituals and processions. During this time, the temple fills with activity from early morning until late evening.

The temple is open during the day and in the evening, so a morning or late afternoon visit both work well. As in most Hindu temples, visitors are expected to remove their footwear before entering and to dress modestly.

The name Acharapakkam derives from Achu (caster bolt) and Pakkam (broken pieces), recalling how Ganesha broke the chariot's caster bolt after being left out of the Tripura war; Shiva then granted him good deeds before defeating the Asuras at Thiruvathigai. The same legend is told at Thiruvathigai Veerattaneswarar Temple and Thiruvirkolam Sri Tripuranthaka Swami temple.
