Shabiha (Levantine Arabic: شَبِّيحَة Šabbīḥa, pronounced [ʃabˈbiːħa]; also romanized Shabeeha or Shabbiha; lit. 'thugs') is a colloquial and generally derogatory term for various loosely-organised Syrian militias loyal to the Ba'athist government and the Assad family prior to the regime's collapse in 2024, used particularly during the initial phase of the Syrian civil war. As the war evolved, many groups that had previously been considered shabiha were amalgamated into the National Defence Force (NDF) and other paramilitary groups.

The mercenaries consisted of mostly Alawite men paid by the regime to eliminate figures of its domestic opposition and alleged fifth-columnists. The Shabiha were established in the 1980s to smuggle weapons to the Syrian soldiers stationed in Lebanon during the Lebanese Civil War and Syrian occupation of Lebanon. While most Shabiha were members of the Alawite minority, the main common denominator of the groups was loyalty to the Assad family rather than religion, and in areas such as Aleppo they were primarily Sunni.

The Shabiha were founded in the 1980s by Nimir al-Assad (President Hafez al-Assad's cousin) and Rifaat al-Assad (Hafez al-Assad's brother). They were originally concentrated in the Syrian coastal region around Latakia, Baniyas, and Tartous, where they profited from smuggling through the region's ports.

Known by Alawites in Syria as an Alawite gang, during the late 1980s and early 1990s they smuggled food, cigarettes, and other goods, with government support, from Syria to Lebanon and sold them for considerable profit. Luxury cars, weapons, and drugs were smuggled in the opposite direction, from Lebanon to Syria. The Shabiha are loyal to various members of Syria's ruling Assad family. They remain untouchable and unarrested, operating with impunity from the Syrian authorities. The Shabiha gained notoriety in the 1990s for the brutality they imposed on the Syrian coast.

The word became common in the 1990s, when it was being used to refer to "thugs" who worked with the government and often drove Mercedes-Benz S-Class and gave their guards the same car; that specific car model was nicknamed Shabah (Ghost) in many Arabic countries which led to its drivers being called Shabeeh. The Syrian opposition stated that the shabiha are a tool of the government for cracking down on dissent. The Syrian Observatory for Human Rights has stated that some of the shabiha are mercenaries. Strongly loyal to the Assad regime and containing anti-Sunni factions, shabiha militias are discreetly financed by powerful Syrian businessmen, and have often been responsible for the more brutal actions against the opposition, including possible massacres. Psychological warfare against Syria's Sunni population is also known to have been employed by Alawi Shabiha, which includes demonising Sunni religious beliefs and usage of deriding slogans such as "There is no God but Bashar".

Shabiha, thugs, and other such terms are not a new phenomenon. During the Arab Spring revolutions, they were used politically by some governments and influential individuals to disrupt the revolutions and intimidate the rebels and demonstrators. Enemies of the revolutions also attempted to use gangs to further their political and religious goals.

According to defectors privately interviewed by The Star in 2012, 'Shabiha mercenaries' were established in the 1980s by Rifaat al-Assad and Namir al-Assad, President Hafez al-Assad's brother and cousin. They were originally concentrated in the Mediterranean region of Syria around Latakia, Banias and Tartous, where they allegedly benefited from smuggling through the ports in the area. The shabiha, who were named for the Arabic word for ghost or for the Mercedes-Benz W140 that was popular for its smuggling sized trunk and was called the Shabah, were known by the Alawites in Syria as Alawi ganglords. During the late 1980s and early 1990s, they smuggled food, cigarettes and commodities, subsidized by the government, from Syria into Lebanon and sold them for a massive profit, while luxury cars, guns and drugs were smuggled in reverse from Lebanon up the Bekaa Valley and into Syria's state controlled economy.

The shabiha guards, who each had loyalty to different members of the extended Assad family, were untouchable and operated with impunity from the local authorities. They gained notoriety in the 1990s for the brutal way they enforced their protection rackets in Latakia and were noted for their cruelty and blind devotion to their leaders. By the mid-1990s, they had gotten out of hand, and President Hafez al-Assad had his son Bassel al-Assad clamp down on them, which he did successfully. In 2000, when Bashar al-Assad came to power, they were apparently disbanded, but following the uprising that began in March 2011, the shabiha gangs, which evolved into the shabiha militias, were again approved by Assad's government.
