Nambiyaar is a 2016 Tamil language comedy film written and directed by Ganeshaa in his directorial debut.^[1] It stars Srikanth and Sunaina in the lead roles alongside Santhanam as the title character. Produced by Srikanth's home production Golden Friday Films and independent producer, Haresh Vikram Vijayakumar (Malaysia), the film is named after the veteran actor M. N. Nambiar, who was famous for his villainous roles in yesteryear Tamil cinema.

Vijay Antony scored the soundtrack and original scores for the film,^[2] while M. S. Prabhu handled the cinematography and Vivek Harshan did the editing. Despite beginning production during early 2013, the film went through delays before releasing in August 2016. This is the last film of Santhanam acting as comedian.

Ganesh, a former assistant to directors S. S. Rajamouli and Vikraman, announced plans in February 2013 that he would be making a film named Nambiar and had approached actor-music composer Vijay Antony to play the title role. However, due to his prior commitments, he turned down the lead role and agreed to compose music for the film. Subsequently, Srikanth signed the film and agreed to make it his maiden production venture. Comedy actor Santhanam was approached to play another role sharing the same screen length with the lead actor. Actress Sunaina was signed in to play the female lead role. Srikanth's wife Vandana made her entry as the costume designer of the film.^[3] Arya was asked to play an important guest role and shot for the film without demanding a remuneration.^[4]

Ganesh called this as his "dream project" and also approached Mohan Nambiar, son of veteran villain actor Nambiar and got formal permission from him before naming the film after the actor.^[5] The shoot of the first schedule of the film was happening in Chennai in June 2013.^[6] The film's release was delayed for two years, before the makers readied the project for release in August 2016.^[7]

Music was composed by Vijay Antony composing for a Srikanth film for the second time after Rasikkum Seemane. Actor Santhanam made his debut as singer with this film.^[8][9]
