Naina is a 2005 Indian Hindi-language supernatural horror film directed by Shripal Morakhia and starring Urmila Matondkar as the titular character who loses her sight as a child, regains it as an adult with corneal transplantation and starts seeing images beyond the general surroundings. The film is an unofficial remake of the 2002 Hong Kong-Singaporean horror film The Eye directed by the Pang brothers, with a subplot borrowed from the 2002 Japanese film Dark Water.

The film was premiered in the Marché du Film section of the 2005 Cannes Film Festival. Released theatrically on 20 May 2005, Naina flopped at the box office, grossing ₹6.94 crore against a ₹5 crore budget. It was also controversial because its depiction of the protagonist seeing ghosts after receiving a corneal transplantation was similar to existing fears in India surrounding corneal transplants and it was feared the film would discourage people from donating corneas or seeking corneal transplants.
