The Sadrist Movement (Arabic: التيار الصدري al-Tayyār al-Sadrī) is an Iraqi Shi'a Islamic national movement and political party, led by Muqtada al-Sadr.

The Sadrist Movement ended as largest political party in the October 2021 Iraqi parliamentary election, with 73 seats in Parliament, but in June 2022, during the 2022 Iraqi political crisis, Muqtada al-Sadr’s bloc resigned from parliament.^[4]

During the 2009 Iraqi governorate elections Sadrists ran under the name Independent Free Movement.

During the 2010 Iraqi parliamentary election Sadrists were part of the National Iraqi Alliance.

In a press conference on 6 March 2010 ahead of the 2010 Iraqi parliamentary election, Muqtada al-Sadr called on all Iraqis to participate in the election and support those who seek the withdrawal of U.S. troops from the country. Al-Sadr warned that any interference by the United States will be unacceptable. Al-Sadr, who has thousands of staunch followers across Iraq has consistently opposed the presence of foreign forces and repeatedly called for an immediate end to the Iraq War.^[8]

Over time, numerous factions in the Sadrist Movement disagreed with Muqtada al-Sadr over various issues and broke off, forming separate militias and parties:

• Asa'ib Ahl al-Haq^[9][10]
• Abu al-Fadl al-Abbas Forces^[9][10]
• Jaysh al-Mu'ammal^[9][10]
• Tashkil al-Hussein al-Tha'ir^[9]
• Kata'ib al-Tayyar al-Risali^[9]
• Islamic Virtue Party^[9]

In October 2012, various Iraqi religious sects joined the conflict in Syria on both sides. Shiites from Iraq, in Babil Governorate and Diyala Governorate, have traveled to Damascus from Tehran, or from the Shiite holy city of Najaf, Iraq, claiming to protect Sayyida Zeinab, an important Shiite shrine in Damascus.^[11] Abu Mohamed, with the Sadrist trend, said he recently received an invitation from the Sadrists' leadership to discuss the shrine in Damascus.^[11] A senior Sadrist official and former member of Parliament, said that convoys of buses from Najaf, under the cover story of pilgrims, were carrying weapons and fighters to Damascus.^[11] Some of the pilgrims were members of Iran's elite Islamic Revolutionary Guards Corps.^[11]

However, later in 2017 following the Khan Shaykhun chemical attack in Syria, Muqtada al-Sadr called for Syria's president Bashar al-Assad to step down from power.^[12][13]

The Sadrist Movement ended as second largest political party in the 30 April 2014 Iraqi parliamentary elections, with 7% of the votes and 34 seats in Parliament. The largest party in those elections was the State of Law Coalition, led by Nouri al-Maliki, which won 24% and 92 seats.

The Sadrist Movement ended as largest party in the 12 May 2018 Iraqi parliamentary elections, with 14.38% of the votes and 54 seats in Parliament.
