Mayur Vihar is an upmarket residential area in East Delhi close to the Noida-Delhi border, situated just across the Yamuna River, and is divided into three distinct phases. As the name suggests, it has been the dwelling (vihar) of peacocks (mayur). Even today, the area has a closed sanctuary dedicated to the conservation of peacocks. This residential area came into existence in 1979–80, back when the trans-Yamuna area, part of today's East Delhi was sparsely populated. The government decided to sell the Delhi Development Authority (DDA) flats to employees of Public Sector Units (PSU's) and semi-PSU's like the BHEL, among others. This was also an experiment to integrate people belonging to various economic bracket's i.e. High Income Group (HIG's), Middle Income Group (MIG's) and Low Income Group (LIG's) in one community. The residential units in Mayur Vihar are a relatively recent phenomenon and were developed in three phases. It is well connected by high-frequency buses and is serviced by the Blue Line and Pink Line of Delhi Metro.

The area is accessible by the Mayur Vihar-I and Mayur Vihar Pocket-1 metro stations. Residential Units Phase I has DDA flats (organized into Pockets I-V) and Housing Co-Operative Society Buildings (e.g., Hindustan Apartments, Upkar Apartments, Ashiyana Apartments, Sadar Apartments, Glaxo Apartments). The first immigrants to Phase I were mainly in Pocket III and Pocket I in the early 1980s. Later, Pocket II, Pocket IV (near metro station) and Pocket V were developed. The nearest village is known as Chilla Gaon that is now surrounded by housing societies. Samachar Apartments is one of the oldest apartments in the locality. People bought land and moved in prior to 1985 at very low costs. Now, the area is considered to be an expensive real estate market with the availability of two metro lines apart from the proximity to both the central business districts of Connaught Place, New Delhi - Barakhamba Road to the east and Sector 15-18 of Noida to the south.
