New Delhi Municipal Council (NDMC; ISO: Naī Dillī Nagarapālikā Pariṣad) is the municipal council of the city of New Delhi, Delhi, India. It covers an area of 42.7 km² under its administration, which is commonly referred as Lutyens' Delhi.

The only owner is the Government of India and about 80% of buildings in New Delhi are owned by the New Delhi Municipal Council area. It is governed by a council headed by a chairperson, who is usually a career civil servant and holds the rank of Joint Secretary to Government of India appointed by the Government of India. The council also includes the Chief Minister of Delhi as an Ex officio member.

It is one of three local bodies in the National Capital Territory of Delhi, the others being Municipal Corporation of Delhi and Delhi Cantonment Board.

NDMC has its origins in the Imperial Delhi Committee which was constituted on 25 March 1913 to overlook the construction of the new capital of India. Thereafter in February 1916 the Chief Commissioner, Delhi, created the Raisina Municipal Committee, which was upgraded to a 2nd class Municipality under the Punjab Municipal Act on 7 April 1925. Then on 22 February 1927, the Committee passed a resolution adopting the name "New Delhi" giving it the name, "New Delhi Municipal Committee", approved by Chief Commissioner on 16 March 1927. In May 1994, the NDMC Act 1994, replaced the Punjab Municipal Act 1911, and the Committee was renamed as the New Delhi Municipal Council.

NDMC's headquarters building, known as Palika Kendra, was built in 1984, and was the tallest building in the city at that time.

In 2014, 17 NDMC employees, including members of the civil department, were suspended after contractor-led sting operations uncovered evidence of corruption and unethical behavior. Video and audio recordings suggested systematic malpractice, mostly involving lower-ranking staff but implicating at least one assistant engineer. Investigations were launched to confirm the veracity of the evidence and to determine accountability.

According to The Indian Express In February 2023, the Ministry of Home Affairs approved the regularization of approximately 4,500 NDMC employees. This decision aimed to address long-standing demands for job security among Group C employees. Delhi Chief Minister Arvind Kejriwal had advocated for the approval of recruitment rules to facilitate this regularization process.
