The Eparchy of Palai is a Syro-Malabar Catholic ecclesiastical jurisdiction or eparchy of the Catholic Church with an area of 1166 km2[1] comprising the Meenachil taluk and a few villages of the neighbouring taluks in Kottayam, Ernakulam, and Idukki districts of central Kerala in South India.

The faithful of this eparchy, numbering 326,742, belong to the ancient St. Thomas Christian community.

The seat of the bishop is the St. Thomas Cathedral based in the town of Palai.

The then apostolic nuncio to India, Archbishop Leo P. Kierkels, installed Sebastian Vayalil as the first bishop of the new eparchy.

Pope Pius XII, by the Bull "Quo Ecclesiarum", issued on 25 July 1950, bifurcated the eparchy of Changanacherry and out of the territory covered by the then Foranes of Palai, Muttuchira, Kuravilangad, Anakkallu, and Ramapuram erected the eparchy of Palai as a suffragan of the Archeparchy of Ernakulam.

Leo P. Kierkels, the Apostolic Internuncio in India, published the Bull in the St. Thomas Cathedral Palai on 4 January 1951 and installed Sebastian Vayalil as the first bishop of the new eparchy.
