Ayatollah Sheikh Nimr Baqir al-Nimr (21 June 1959 – 2 January 2016), 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.
He was popular among youth and critical of the Saudi Arabian government, advocating for free elections in Saudi Arabia. In 2006, al-Nimr was arrested by Saudi authorities, during which he claimed to have been beaten by the Mabahith, a Saudi secret police agency. In 2009, he criticized Saudi authorities and suggested that if the rights of Saudi Shia were not respected, the Eastern Province should secede. In response, Saudi authorities arrested al-Nimr along with 35 others.
