South is one of the four cardinal or compass directions. It is the opposite of north and at right angles to east and west.

True south is the direction towards the southern end of the axis about which the earth rotates, called the South Pole. The South Pole is located in Antarctica. Magnetic south is the direction towards the south magnetic pole, some distance away from the south geographic pole.

It is the direction to the right of an observer facing east.
