Irinjalakuda is a Municipal town in Thrissur district, Kerala, India. Irinjalakuda is the headquarters of Mukundapuram Taluk. Irinjalakuda is known for the Koodalmanikyam Temple and the Thachudaya Kaimals who had princely status until 1971.
The name Irinjalakuda has been derived from "Iru" and "Chaal", meaning two streams. According to another legend, the origin of the name Irinjalakuda came from 'Irinjalikoodal'. 'Koodal' simply means merge, merging of two rivers.So it shows that Irinjalakuda may have gradually developed, from 'Irinjalikoodal', that derived from 'Inangikoodal', means merge. At present there is no river in Irinjalakuda, only the myth of river.
