In electrostatics, neutral point is the point in space between two like charges where the net electric feld due to the charges is zero.

In magnetostatics, when we use a magnetic compass to trace the magnetic field lines of a bar magnet we obtain two pairs of points where the magnetic compass detects no net magnetic field.

One such pair of points is obtained when the North pole of the bar magnet points South and another such pair of points is obtained when the North pole of the bar magnet points the North.

These points are called neutral points.

In thermoelectricity neutral point is a point in the temperature scale for which the thermoelectric power of the two metals used becomes zero. If the temperature given to the junctions of the metals are equally more and less than the neutral point, then no current or potential difference will be produced.
