Ilamai Oonjal Adukirathu (English: Youth is swinging) is a 1978 Tamil-language Indian film directed by C. V. Sridhar. It has Kamal Hassan and Sripriya in lead roles with Rajinikanth and Jayachitra in supporting roles. It had a 175-day run at the box office. The film was later remade in Telugu as Vayasu Pilichindi (1978) and in Hindi as Dil-E-Nadaan (1982).

Prabhu (Kamal Haasan) is brought up by Murali's (Rajinikanth) mother and is the General Manager for Murali's marketing agency at Chennai. Murali treats Prabhu not just as a friend, but as a brother and depends on him for all business decisions. Prabhu is in love with Padma (Sripriya), a college student. Padma's relative Jayanthi (Jayachitra) is a young widow who works at Murali's office. Murali, an alcoholic, with a roving eye is not aware of Prabhu's love for Padma. Padma is the only girl who rejects Murali's advances. Though Jayanthi knows about the love affair between Prabhu and Padma, Prabhu's presence stimulates her sexually. Once she accompanies Prabhu and Padma for a film screening and unable to control her sexual feelings, comes out. Murali offers her a lift in his car; both get excited in the privacy of the car, but suddenly feel guilty about the incident.

A disturbed Jayanthi avails leave and goes to her village and Padma joins her, as Prabhu goes on an official tour. Prabhu, planning to surprise Padma, proceeds to Jayanthi's village to meet Padma. When Prabhu lands at Jayanthi's home, she is alone as Padma has gone to attend a wedding in a nearby village. Jayanthi convinces Prabhu to stay back overnight, so that he can meet Padma the next day. Jayanthi arouses Prabhu in the night and they make love. Prabhu, feeling guilty about the whole event, writes a letter of apology to Jayanthi and leaves. Devastated to read the note when she returns to Jayanthi's house, Padma returns to Chennai, where she starts distancing herself from Prabhu without revealing why.
