Nambiyaar is a 2016 Tamil language comedy film written and directed by Ganeshaa in his directorial debut. It stars Srikanth, Santhanam (as the title character) and Sunaina in the lead roles. 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, 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.
