The Koker trilogy is a series of three films directed by acclaimed Iranian filmmaker Abbas Kiarostami: "Where Is the Friend's Home?
" (1987), "And Life Goes On" (a.k.a. "Life and Nothing More", 1992) and "Through the Olive Trees" (1994).
 The designation was made by film theorists and critics, rather than by Kiarostami himself, who resists the designation and notes that the films are connected only by the accident of place (referring to the fact that Koker is the name of a northern Iranian village).
 He has suggested that it might be more appropriate to consider the latter two titles plus "Taste of Cherry" (1997) as a trilogy, since these are connected by the theme of life's preciousness.
