The '''Deputy Chief Minister of Tamil Nadu''' is the deputy to the [[Chief Minister of Tamil Nadu]], who is head of the [[government of Tamil Nadu]]. The deputy chief minister is the second highest ranking member of the [[Tamil Nadu Council of Ministers]].<ref name="dpmconsti">{{cite news|url=http://www.thehindu.com/news/national/of-deputy-chief-ministers-and-the-constitution/article3632410.ece|title=Of Deputy Chief Ministers and the Constitution|access-date=7 November 2017|newspaper=The Hindu|date=2012-07-13|last1=Rajendran|first1=S.}}</ref> A deputy chief minister also holds a cabinet portfolio in the state ministry. In the [[Tamil Nadu Legislature|legislative assembly system]] of government, the [[Chief minister (India)|chief minister]] is treated as the "first among equals" in the cabinet; the position of deputy chief minister is used to govern the state with the support of a single party member or to bring political stability and strength within a [[coalition government]], or in times of state emergency, when a proper [[command hierarchy|chain of command]] is necessary. On multiple occasions, proposals have arisen to make the post permanent, but without result. The same goes for the post of deputy prime minister at the national level.

The office has since been only intermittently occupied, having been occupied for a little more than 5 years out of the 12 years since its inauguration. Since 2009 Tamil Nadu has had 2 deputy chief ministers, of which none having at least one full term. The first was former chief minister of Tamil Nadu [[M. Karunanidhi]]'s third son [[M. K. Stalin]]<ref name="Stalin appointed as first Deputy CM of Tamil Nadu">{{cite web | url=http://www.thehindu.com/todays-paper/karunanidhi-makes-stalin-deputy-chief-minister/article293666.ece | title=Karunanidhi makes Stalin Deputy Chief Minister | work=[[The Hindu]] | access-date=30 May 2009}}</ref> of the [[Dravida Munnetra Kazhagam]] party, who was sworn in on 29 May 2009, also home minister in Karunanidhi's [[13th Tamil Nadu Assembly|fifth ministry]]. The post was vacant until [[O.

Palaniswami]]'s government, Also he remains Tamil Nadu's longest-serving deputy chief minister and was the last person to serve as the deputy chief minister of Tamil Nadu until the post became vacant.
