A royal decree "decided to relieve Emir Jalwi bin Abdulaziz bin Musaid al-Saud" from his post and transfer him to Najran region bordering Yemen, the Saudi Press Agency reported without further explanation.
Seven Shias, including children, were gunned down in the eastern town of Al-Dalwa last week during the commemoration of Ashura.
Political and religious leaders in the Sunni-dominated kingdom condemned the incident, which the cabinet said "threatened security and stability of citizens by terrorists."
Two members of the security forces have been killed in a gun battle with suspects and more than 30 people detained in a dragnet since the November 3 attack, according to local media.
Although there had been attacks on Westerners and government targets in the kingdom between 2003 and 2006, it was the first major militant strike against Shias in Saudi Arabia.
Following the killings, a royal decree dismissed Culture and Information Minister Abdulaziz Khoja.
The reasons for his firing remain unclear but it followed Shia calls for action against hate speech in the media.
Since 2011, protests and sporadic attacks on security forces have occurred in Shia-dominated areas of Eastern Province, home to most of the minority community which complains of marginalisation.
