A liquid filter, in particular for oil or fuel in an internal combustion engine, with the liquid filter comprising a filter housing with at least one liquid intake passage and at least one liquid return passage, a releasable cover which closes the filter housing liquid-tight, and an individually replaceable filter insert which can be removed from the filter housing. A hollow fastening screw is arranged centrally in the front wall of the filter housing with the front wall facing the filter connecting flange when in the mounted condition, with the fastening screw turnable in relation to the filter housing. The liquid filter may be tightly screwed to a filter connecting flange of, e.g., an internal combustion engine. A longitudinal middle axis of the filter housing and the plane of the front wall are arranged at an angle <90°relative to each other, and the longitudinal middle axis of the fastening screw and the plane of the front wall extend at a right angle towards each other when in the mounted condition.
