Wellington (Native name: Jakkatalla (Badaga)) is a town in the Nilgiris District of the Indian state of Tamil Nadu, located at three kilometres to the north of Coonoor on the NH-181.

The Wellington Cantonment is home to The Madras Regimental Centre (MRC) and The Defence Services Staff College (DSSC).

In 1852, Sir Richard Armstrong, the then Commander-in-Chief, recommended that the name should be changed to Wellington in honour of the Iron Duke, who had previously evinced an interest in the establishment of a sanatorium in the Nilgiris.

Perched atop a plateau of the southern reaches of the Western Ghats, the district shares a common liking among tourists with Kodaikanal, Munnar, Wayanad, and Palakkad.

The topography of the district is hilly and abounds in lush evergreen forests, glens, meadows, downs and tea estates.

The one word that best describes the weather in Coonoor/Wellington is salubrious, a term made famous by the Defence Services Staff College!

The temperature in summer (the dry months of Apr-May) swings between 27 °C by day, and can be a nippy 14 °C at night in the valley bowls; the slopes record around 17–18 °C at night/early mornings.

Air connectivity to Coimbatore exists from Hyderabad (HYD), Delhi (DEL), Mumbai (BOM), Chennai (MAA), Kochi (COK), and Bangalore (BLR).

Traditionally, the second Sunday of the month was organised as a local market, outside the gates of Cordite Factory, located at Aruvankadu/Aravangadu, on the main Coonoor-Ooty road (NH 181).

The local story around the choice of date is to do with the availability of salary in cash, and the second Sunday being best suited to make all necessary purchases for the month.

With the choking of traffic becoming a nuisance, the local market has shifted to the Wellington Stadium, below the Railway Station, and next to the Cantonment Board Office.
