Kolt 15 Gap is a 1971 Yugoslav short documentary film written and directed by Jovan Jovanović and Miodrag Milošević.

In the countryside, Ćebić, together with his father, recounts his early life during the 1941 invasion of Yugoslavia, when he joined the partisans at the age of 15 and then left the village in 1946 in hopes of learning a craft and earning a living, the latter of which he hasn't achieved, blaming it on the Yugoslav State's betrayal of socialist ideals, which he claims should be anti-capitalist.

He does what he refers to as "Kolt 15 Gap", an acronym of "Gathering scraps and licking plates for 15 years actively and passively" (Serbo-Croatian: Kupi otpatke, liže tanjire, 15 godina aktivno i pasivno).

During the final third of the film, Ćebić walks around outside a factory and interviews other workers about their knowledge of Marx and Engels and their satisfaction with their jobs, pay and living conditions, before he and the camera operator are forced to leave.

It is at times more reminiscent of a pseudo-documentary and it is often comical in tone due to some of Ćebić's more absurd musings about life and politics.
