Kolkata Dakshin Lok Sabha constituency (earlier known as Calcutta South Lok Sabha constituency) is one of the 543 Lok Sabha (parliamentary) constituencies in India. The constituency centres on the southern part of Kolkata in West Bengal. While four of the seven legislative assembly segments on No. 23 Kolkata Dakshin Lok Sabha constituency are in Kolkata district, three are in South 24 Parganas district.
Considered to be a bastion of the Trinamool Congress, it has been won by the party since its formation in 1998. Prior to it, the seat was a stronghold of Indian National Congress. TMC's founder and former chief minister of West Bengal, Mamata Banerjee was the longest holder of the seat.
On 5 June 2026, MP Mala Roy switched her political party from Trinamool Congress to Nationalist Citizens Party of India (NCPI), which led to the end of the 28- year rule (for the first 17 years, it was known as Calcutta South) of the Trinamool Congress.
