Where Is the Friend's House? (Persian: خانه دوست کجاست, Khane-ye dust kojast) is a 1987 Iranian drama film written and directed by Abbas Kiarostami. The plot depicts a conscientious schoolboy's attempt to return his friend's school notebook to his home in a neighboring village, to prevent the friend from being expelled if he fails to hand it in the next day. The film, whose title derives from a poem by Sohrab Sepehri, is the first installment in Kiarostami's Koker trilogy, followed by And Life Goes On and Through the Olive Trees, all of which take place in Koker, Iran.
