The 60th parallel south is a circle of latitude that is 60 degrees south of the Earth's equatorial plane. No land lies on the parallel - it crosses nothing but ocean.

The parallel marks the northern limit of the Southern Ocean and the Antarctic Treaty System. It also marks the southern boundary of the South Pacific Nuclear-Weapon-Free Zone and the Latin American Nuclear-Weapon-Free Zone.

The latitudes below this parallel are often referred to as the Screaming 60's due to the prevailing, high-speed, westerly winds which can generate large waves in excess of 50 feet and peak wind speeds over 90mph.

Starting at the Prime Meridian and heading eastwards, the parallel 60° south passes through:
