An electromotive linear drive (10), in particular for adjusting parts of an item of furniture, having a multi-part housing (14) which is produced from plastic in an injection-molding process and in which are mounted at least one drive train and a block-shaped spindle nut (13) which engages at least partially around the housing (14) and/or at least partially into the housing, should be designed such that the structural design is extremely simple and can furthermore, for installation in particular into a chair, be produced in a compact and also cheap manner from as few components as possible. According to the invention, the housing (14) is formed from at least two housing parts (14a and 14b) and has sliding tracks for the spindle nut (13), wherein at least the thread flights of the spindle (12) are arranged outside the housing (14). In one preferred embodiment, the housing (14) is arranged below the region of the spindle (12) in relation to the assembled position of the electromotive linear drive. The housing parts (14a and 14b) forming the housing (14) are of identical or similar, preferably shell-shaped, design in cross section.
