Ellalan ( Tamil: எல்லாளன், Ellāḷaṉ), ( Sinhala: එළාර, Elara) was a member of the Chola dynasty, who upon capturing the throne became king of the Anuradhapura Kingdom, in present day Sri Lanka, from 205-161 BCE.
Ellāḷaṉ is traditionally presented as being a just king even by the Sinhalese. The Mahavamsa states that he ruled 'with even justice toward friend and foe, on occasions of disputes at law, and elaborates how he even ordered the execution of his son on the basis of a heinous religious crime. Ellāḷaṉ is a peculiar figure in the history of Sri Lanka and one with particular resonance given the ongoing ethnic strife in the country. Although he was an invader, he is often regarded as one of Sri Lanka's wisest and most just monarchs, as highlighted in the ancient Sinhalese chronicle, the Mahavamsa. According to the chronicle, even Ellāḷaṉ's nemesis Dutugamunu had a great respect for him, and ordered a monument be built where Ellāḷaṉ was cremated after dying in battle. Often referred to as 'the Just King'. The Tamil name Ellāḷaṉ means 'the one who rules the boundary".
