Dor (Hindi pronunciation: [ɖoːɾ]; transl. String) is a 2006 Indian Hindi-language drama film written and directed by Nagesh Kukunoor and features Ayesha Takia, Gul Panag and Shreyas Talpade as the lead actors. The film is an official remake of the Malayalam film, Perumazhakkalam (2004) and was well received by the critics after its release on 22 September 2006.

Dor, which was produced by Elahe Hiptoola, had cinematography by Sudeep Chatterjee and editing by Sanjib Datta. For a film that had Hindi as the predominant language with a sporadic use of Urdu, Salim–Sulaiman composed the background score.

The story is about two women who come from different backgrounds and how fate brings them together. Meera (Ayesha Takia), a young woman who becomes a widow shortly after marriage, is trapped by tradition. Zeenat (Gul Panag), on the other hand, faces the daunting task of saving the life of her husband, who is on trial for murder. A bahuroopiya (Shreyas Talpade) helps her reach Meera, who holds the "string" to Zeenat's hope. The companionship that develops between Meera and Zeenat results in redemption for both.
