The town is believed to be of significant antiquity and has been ruled by the Medieval Cholas, Later Cholas, Later Pandyas, the Vijayanagar Empire, the Marathas and the British. The Tamil trinity of Carnatic music; Arunachala Kavirayar (1711–78), Muthu Thandavar (1525–1600) and Marimutthu Pillai (1712–87), originated from Sirkazhi. The Saiva saint Tirugnanasambandar, foremost of the Saiva Nayanars, was born here in the seventh century. Thirumangai Alvar Kaliyan (Thirumangai) was born in Thirukuraiyalur near Sirkazhi. The history of the town is centred on the Sattainathar Temple, which is dedicated to Hindu god Shiva. Also the history of town is associated with Rajarajeshwari – Angalaparameshwari Temple, which is dedicated to Goddess Adi shakthi, who believed to be most powerful form, located in the south of Kalumalaiyar river. The goddess when takes the forceful form, termed as "Shri Kali" or "Pechi amma" or " Angali" which forms the basis for the town's name as "Sirkali".

In ancient times, this town had twelve different names, including Brahmapuram, Venupuram, Thonipuram, Kazhumalam, Pugali, Sirkazhiswaram and Shri Kali. According to Hindu legend, during one of the biggest deluges that submerged the planet earth, Hindu god Shiva is said to have carried the 64 arts on a raft (called Thoni in Tamil). The presiding deity in the temple, Shiva, is thus called "Thoniappar" (the one who carried the raft) and the region is called "Thonipuram". The Hindu god Brahma is believed to have worshiped Shiva here, giving the name "Bhrahmapureeswarar" (the one worshipped by Brahma) and so the region is also referred as "Brahmapureeswaram".

Shiva is believed to have quelled the arrogance of Hindu god Vishnu, after showing his dominance over the three worlds and hence got the name "Sattainathar" here. The town is thus called "Sattainathapuram", which in modern times, is a suburb within Sirkazhi. The town was known as "Kalumalam" during the early Chola period. Thirugnanasambandar, the seventh century Saiva nayanar, as an infant is believed to have been fed with the milk of wisdom by the divine mother Parvati on the banks of the temple tank. The child Sambandar started singing the anthology of Tevaram hymns from then on, commencing with "Todudaiya Seviyan". Sambandar refers the town as "Kazhi" in his verses. It was called Shiyali during British rule, and after Independence, it was renamed "Sirkazhi".
