Gandhi Nagar is a neighbourhood in Adyar, in the south eastern part of the Indian city of Chennai. It is among the most upscale neighborhoods in Chennai. Property prices in Gandhi Nagar have been increasing significantly. It is bordered by the Adyar River, Kasturba Nagar, Kotturpuram, Indira Nagar and the Buckingham canal. Today Gandhi Nagar is a commercial hot spot having relatively good transport and other facilities.

Gandhi Nagar has more than 150 years of history. The oldest landmarks in Gandhi Nagar are the Pillaiyar Kovil and the St. Patrick's School. It was established as 'Gandhi Gram' in January 1948, just a week before Mahatma Gandhi was assassinated. Gandhi Nagar is one of the earliest planned layouts in the erstwhile Madras with more than 322 housing plots, underground drainage systems and broad roads. The neighborhood began its transformation towards becoming a residential locality around 1949 when the first residents are believed to have moved in.

The first residential (non academic) inhabitants are people from a tiny town called Sadhuranga pattinam (சதுரங்கப்பட்டினம்) or Sadras as it is called. They came from Chengulpet to Gandhi Nagar via Buckingham canal via boats that was propelled by wind under favorable conditions or the boats were pulled by humans with rope from boat tied to their waist. At that time in 1942, Gandhi Nagar had lush paddy fields and was used for agriculture and was bordered by Guindy forest (which has almost disappeared now).

The Alwaris family is said to be the first family who resided in Gandhi Nagar.

The next was the family of Mudaliar Brothers. The Mudaliar Brothers consisted of Mr. S.K. Ramachandra Mudaliar and Mr. S.K.Puniyakoti Mudaliar. They worked in Triplicane, but bought vast lands in Gandhi Nagar as their building construction flourished. In one of their lands stands the old cancer institute, which was donated by Mr. S.K. Puniyakoti Mudaliar. Mr. Puniyakoti Mudaliar built first independent flats in Gandhi Nagar. The Mudaliar brothers construction industry recruited people from Sathurangapattinam (Sadras), the first workers settled on banks of Adyar River, this settlement was later called Malligai Poo Nagar.

Dr.A.Ramachandran was another personality who was one among the few who chose to purchase a house in 1954 and reside in Gandhi Nagar. He was a famous Veterinary Doctor and Surgeon who was often visited by people from all walks of life including Politicians, Film Personalities of yesteryear's and normal people alike. He was serving the Government & was assigned specific tasks to enhance care of the wild and mammals. 

The Mudaliar Brothers (S.K.Ramachandra Mudaliar and S.K.Puniyakoti Mudaliar) were building contractors. They needed manpower to execute their projects. Hence people (primarily from Sathurangapattinam) were bought in. They settled on the banks of Adyar river. The laborer settlement attracted more people, thus a community was formed and was named Malligai Poo Nagar which means jasmine flower settlement.
