Where Is the Friend's Home? (Persian: خانه دوست کجاست؟, Khane-ye doust kodjast?) is a 1987 Iranian film directed and written by Iranian director Abbas Kiarostami. The title of the film was derived from a poem by Sohrab Sepehri. It is considered the first film in Kiarostami's Koker trilogy.
The film tells a deceptively simple account of a conscientious schoolboy's quest to return his friend's notebook in a neighboring village, since, should his friend fail to hand it in the next day, it is likely he will get expelled. Hence this film has been seen as a metaphor for the sense of civil duty, about loyalty and everyday heroics. The traditional beliefs of Iranian rural people are also shown in many parts of the movie.
