General Kumaramangalam Colony (also known as G.K.M. Colony) is a sub-neighbourhood of Perambur, Chennai. It was initially created as a residential area for ex-Military persons. It is named after Paramasiva Prabhakar Kumaramangalam, a former Indian Army Chief of Staff.

This area is also known as "Butt Medu", as there used to be small hill made of mud for the army people to practice shooting and once the military camps were removed in early 70's, the mud hill was made flat and the new residential area was developed.

The area goes from the right side of Perambur Loco Works railway station end to the Villivakkam railway station. This place forms a part of the newly created Constituency "Kolathur".

The area was basically developed as residential, but now a few small commercial establishments have emerged.

• • Villivakkam
  • Kolathur (Chennai)
  • Periyar Nagar
  • Peravallur
  • Jawahar Nagar
  • Agaram, Chennai
  • Thiru. Vi. Ka. Nagar
  • Sembium
  • Perambur
  • Ayanavaram

There are Temples, Churches, Mosques and many catholic grottos.

A small pond in between street 9 and street 10 & a large pond between street 24 and street 25 serve the people for their needs.

Though the infrastructure is reasonable, the Public Road Transport is not well developed. The community is depending on buses from either Villivakkam, I C F or Periyar Nagar Bus Terminus. Further connecting to this area from South West is hindered by a Level Crossing (which is the first level crossing in the route from Chennai Central towards Bangalore).

Nearby Bus terminuses include Thiru.Vi.Ka. Nagar bus terminus and Perambur bus terminus.

There is a railway station nearby called Perambur Loco Works railway station. Other nearer railway stations are Villivakkam railway station, Perambur Carriage Works railway station and Perambur railway station.

There are two Chennai Schools and a few government run Kindergartens (Balvadis).

There is also a public hospital nearby.

There is a temple for former Chief Minister of TamilNadu, Dr. M.G.R.; this is the first temple for an actor in Tamil Nadu.

There is a family of Anglo-Tamil decent living in 8th street.
