SS Oceana was a P&O passenger liner and cargo vessel, launched in 1887 by Harland and Wolff of Belfast and completed in 1888. Originally assigned to carry passengers and mail between London and Australia, she was later assigned to routes between London and British India. On 16 March 1912 the ship collided in the Strait of Dover with the Pisagua, a 2,850 GRT German-registered four-masted steel-hulled barque. As a result Oceana sank off Beachy Head on the East Sussex coast, with the loss of 17 lives.
