A vehicle lamp with a separable multi-housing includes a housing that has a hole formation portion and a rear coupling portion on a rear surface of a housing body. The housing body has an internal space in which a module (e.g., an after-sale service target) is positioned and the internal space is covered by a lens. A light source unit can be securely held on the hole formation portion, and the module is taken out through the hole formation portion. The rear coupling portion is formed along an entire circumference of the hole formation portion at an edge of the housing body in such a manner as to have a protrusion structure. An operation of replacing the module can be performed through the hole formation portion. Particularly, a multi-housing can be coupled to the rear coupling portion using a replaceable housing meltable item, thereby covering the hole formation portion.
