Lasantha Manilal Wickrematunge (5 April 1958 – 8 January 2009) was a Sri Lankan journalist, politician and human rights activist who was assassinated in January 2009.

Wickrematunge was the founder of The Sunday Leader and Leader Publications alongside his brother and was known for taking "governments of all hues to task", was a "virulent critic of the Mahinda Rajapaksa government", and had been "locked in a legal battle with the president's brother, defense secretary Gotabaya Rajapaksa, who was spearheading the battle against the LTTE rebels.

Wickrematunge's assassination caused a national frenzy being the country's most influential media personnel and one of the biggest political figures and raised questions about freedom of expression in the country. Wickrematunge's murder was widely condemned across the world. The Daily Mirror called it the "biggest blow" to media freedom in Sri Lanka, and the Editors Guild held the government responsible for the killing as it has failed to stop attacks against media personnel. The government also expressed shock at the killing, pledging to do everything in its power to catch his killers. Wickrematunge had been on Amnesty International's endangered list since 1998, when anti-tank shells were fired on his house.
