Is the north pole a negative charge?

Magnets are said to have a "north pole" and a "south pole". Traditionally, the north pole of a magnet is the side that would be attracted toward the North Pole of the Earth in a compass. Since opposite magnetic poles attract, the Earth's "Magnetic North Pole" is physically a magnetic south pole.

To answer the question... No, the north pole is not a negative charge. We speak of north and south poles in magnetism. We speak of positive and negative charges in electrostatics.
