Sahassa Malla (also known as "The lion hearted king") was King of Polonnaruwa in the thirteenth century, who ruled from 1200 to 1202. He succeeded Lilavati as king of Polonnaruwa, who was removed from the throne by her co-Ministers. He was deposed by General Ayasmantha and succeeded by Kalyanavati. He was the younger brother of Nissanka Malla.

Polonnaruwa (Sinhalese - පොළොන්නරුව, Tamil - பொலநறுவை, previously "ஜனநாதமண்டலம்") was an ancient kingdom in Sri Lanka.
The second most ancient of Sri Lanka's kingdoms, Polonnaruwa was first declared the capital city by King Vijayabahu I, who defeated the Chola invaders in 1070 AD to reunite the country once more under a local leader.
