Kallara is a small town in the Kottayam district in Kerala, India. Kottayam is located 10 km (6.2 mi) m south.

The name Kallara came from the word "kallukaludae Ara". The history of Kallara dates back to the first ever temple or devasthana called Pandavar Kulangara Sreekrishna Swamy Kshetram and Kallara Kavu.
