Chatterjee/Chatarjee (sometimes Chatterji or Chatterjea or chatarjee) Chêṭarji) is an Indian family name of the Bengali Brahmin caste. It is a variant of Chattopadhyay(a). Chattopadhyay (compound of village name "Chaṭṭa" and "upādhyāya" denoting "priest, teacher" originally granted with the village named Chaṭṭa) is the Sanskritized form of the local Prakrit word "chaturjye", anglicized to Chatterjee. Upadhyays from Chattol area of gangetic Bengals were popularly known as Chattopadhyay or Chatterjee. The renowned 19th century mystic Gadadhar Chattopadhyay or Sri Ramakrishna is from this caste.
Chatterjees or Chatarjees are from the ancient Kashyap Gotra, which means all Chatterjees are descended from the ancient sage Kashyapa, son of Marichi as per the Puranas. Together with Mukherjees, Banerjees, Bhattacharjees and Gangulys, Chatterjees form the Kulin Brahmins, the highest tier of the Bengali caste system.
