Jayanagar is the first post-independence planned residential area. It is a residential and commercial neighbourhood in Bengaluru city. Jayanagar comprises ten blocks (including 4th 'T' Block), of which the 3rd and 4th Blocks are largely commercial hubs, while the rest are mostly residential. The name symbolizes the Maharaja of Mysore's first name "Jayachamaraja".
The foundation of Jayanagar was laid in 1948. It was one of the first planned neighbourhoods in Bangalore and at the time, the largest in Asia. A 2010 survey by DNA Bangalore ranked Jayanagar as the most liveable place in Bangalore and still maintains the old charm of the city
Jayanagar was traditionally regarded as the southern end of Bangalore. The "South End Circle", wherein six roads from different areas meet, and the historic Ashoka Pillar bear this fact.
Jayanagar has a number of temples. The Ragigudda temple near East End and the Shree Dharmanath Jain temple near the IV Block bus stand are prominent. The Jayanagar Shopping Complex is in IV Block, next to the Bus Station. The 4th Main road, which is known as Nanda Road, is actually a boulevard running North to South from South End Circle to 46th Cross in 5th Block for almost 2 kilometers and is characterized by well maintained parks on either side.
The current MLA is B.N. Vijayakumar of BJP, won against M.C.Venugopal of Congress.
