Nanami: The Inferno of First Love (初恋・地獄篇, Hatsukoi Jigokuhen), also known as The Inferno of First Love and Nanami, First Love, is a 1968 Japanese drama film directed and written by Susumu Hani. The film competed for the Golden Bear award at the 18th Berlin International Film Festival in 1968.

According to Hani, Shūji Terayama, known as an underground dramatist at the time, was approached to work on the film but considered the synopsis Hani provided already complete. At the insistence of his investor, Hani later asked Terayama to lend his name to the film for his appeal among younger audiences.
