St. Mary' Church is the main catholic ward in the city of Noida, India and is devoted to the Assumption of Our Lady. It goes under the Agra Diocese of the Roman Catholic Church. The area lies on the north-western tip of Agra Diocese, circumscribing with the Delhi Diocese on the west and Meerut Diocese on the north. The present ward minister of the congregation is Fr. Joseph Dabre. Catholics hunting down occupations were living in the modern city of Noida since its constitution in 1976 by the UP Industrial Development Act. At first they went to close-by places of worship in Delhi particularly Mayur Vihar for going to Mass.
On the request of Noida Catholics, the cleric from Mayur Vihar area later consented to commend the Mass on Saturday nights in Noida as he must be in his ward on Sundays. Because of absence of an appropriate place, it was organized in the places of various individuals. The congregation by and by stands in Sector – 34, simply close to the Ram Mandir. There is a neighborhood shopping complex where a Mother Dairy stall is likewise arranged. The congregation is arranged under 1 kilometer from Noida City Center metro station. The establishment stone for the congregation was laid on 15 August 1991 by the then Archbishop of Agra Diocese.
