Park Street, officially known as Mother Teresa Sarani, is a famous thoroughfare in downtown Kolkata (formerly Calcutta), India. The street runs through what was a deer park of Sir Elijah Impey, Chief Justice of the Supreme Court in Calcutta from 1773 to 1789, hence the earlier name. Its current official name was given by Kolkata Municipal Corporation in honour of Mother Teresa. It's located in central Kolkata.
