Unruled Paper (Persian: کاغذ بی‌خط, Kāghaz-e bi Khatt) is a 2002 Iranian film directed by Nāser Taghvā'i (his first after twelve years), based on an original script by Nāser Taghvā'i and Minoo Farsh'chi. The film was produced in 2001 by Yektā Film.The principal roles in the film are played by Khosrow Shakibai (Jahāngir) and Hadyeh Tehrani (Royā). For his role, Khosrow Shakibai was nominated for the Crystal Phoenix Award, in the category of men, at the 20th Fajr International Film Festival in 2001, received the second Best Actor Of The Year Award From Writers and Critics, in the category of men, in 2002, and was awarded the Golden Tablet from Iran Actor Site in 2003. Hadyeh Tehrani's acting in this film has been praised by many critics as equally superb and laudable. For her role, she was nominated for the Crystal Phoenix Award, in the category of women, at the 20th Fajr International Film Festival in 2001. The title of the film is derived from a remark by Royā that she never was able to write neatly on a ruled paper, but this changed when she wrote on unruled paper, thus giving voice to the blessings of freedom.

The film, with a strong cast of Iranian actors, received critical acclaim in Iran: Various critics have described the movie's dialogues as pithy and thought-provoking, and the language used as both natural and powerful. The quality of the acting and directing have both been praised as well. Taghvā'i attempts to pay attention to the most minute details of the film (for instance, the accuracy with which the separate consecutive shuts match, or the precision of the angles at which the communicating actors look away from the camera). As Tahmineh Milani once has noted, accuracy of presentation is one of the hallmarks of Nāser Taghvā'i's films. The dialogues of the film are replete with terse remarks and critical commentaries on the contemporary political and social conditions prevailing in Iran.
