Nimr al-Nimr, a prominent Shia cleric in Saudi Arabia, was executed by the Saudi government along with 46 other people.

Ayatollah Sheikh Nimr Baqir al-Nimr, commonly referred to as Sheikh Nimr, was a Saudi Shia sheikh from Al-Awamiyah in Saudi Arabia's Eastern Province. His arrest and execution were widely condemned by various governments and human rights organizations.

Shia Islam is the second-largest branch of Islam. It holds that Muhammad designated Ali ibn Abi Talib as both his political successor (caliph) and as the spiritual leader of the Muslim community (imam). However, his right is understood to have been usurped by a number of Muhammad's companions at the meeting of Saqifa, during which they appointed Abu Bakr as caliph instead. As such, Sunni Muslims believe Abu Bakr, Umar, Uthman and Ali to be 'rightly-guided caliphs', whereas Shia Muslims regard only Ali as the legitimate successor.

Nimr Baqir al-Nimr was a Shia cleric and critic of the government in Saudi Arabia, who was beheaded on 2 January 2016, one of 47 people executed that day for terrorism offenses. Others executed included Sunnis who had been convicted of involvement in terror attacks linked to al-Qaeda which took place in 2003. News of the killings triggered international demonstrations, and condemnation by nations, supranational organizations, and human rights groups.

On January 2, 2016, the Kingdom of Saudi Arabia carried out a mass execution of 47 imprisoned civilians convicted of terrorism in 12 provinces in the country. Forty-three were beheaded and four were executed by firing squads. Among the 47 people killed was Shia Sheikh Nimr al-Nimr. This was the largest mass execution carried out in the kingdom since 1980. Nimr al-Nimr was sentenced to death by the Specialized Criminal Court on 15 October 2014 for "seeking 'foreign meddling' in Saudi Arabia, 'disobeying' its rulers and taking up arms against the security forces". His execution was condemned by religious and political figures and human rights groups. The Saudi government said the body would not be handed over to the family. Al-Nimr was very critical of the Saudi Arabian government, and had called for free elections in Saudi Arabia.
