An automatically cleanable milk filter includes a cylindrical housing with a longitudinal direction and with a cylindrical outer wall, a first end with a first liquid connection, and a second end with a second liquid connection, wherein, during use of the filter, the second end is situated above the first end. A concentric cylindrical filter plate containing a plurality of filter holes with a smallest diameter of between 60 and 100 um and a cylindrical core which is placed concentrically within the filter plate are accommodated in the housing. The filter plate divides the filter volume into a first volume part which is directly connected to the first liquid connection, and a second volume part which is directly connected to the second liquid connection. The second volume part includes a cylindrical part, as well as a top part which narrows at a transition to the second liquid connection. The cylindrical part, viewed in a direction towards the second liquid connection, extends at least a predetermined distance beyond the plurality of holes in the filter plate, and the first volume part, viewed in a direction towards the second liquid connection, does not extend beyond the filter plate. In this way, the stream of cleaning liquid, supplied from above, can develop beyond the top part to form a more turbulent stream parallel to the cylindrical part, and thus a more thorough cleaning of, in particular, the upper filter holes. In addition, a milking device including this milk filter is provided.
