Zviadists was an informal name of supporters of the former Georgian President Zviad Gamsakhurdia, who was overthrown and killed during the Georgian Civil War of 1991–1993.

First President of Georgia Zviad Gamsakhurdia was ousted in a bloody coup that destroyed the center of Tbilisi between 22 December 1991 and 6 January 1992, forcing Gamsakhurdia to flee to neighboring Chechnya. Zviad Gamsakhurdia's supporters, the Zviadists staged mass demonstrations against the post-coup government led by the former Soviet Georgian leader Eduard Shevardnadze in various parts of Georgia and organized armed groups which prevented the government forces from taking control of Samegrelo, the ex-President's home province. Skirmishes between pro- and anti-Gamsakhurdia forces lasted throughout 1992 and 1993 and developed into a full-scale civil war with Gamsakhurdia's return to Western Georgia in September 1993. Zviadist rebels were defeated by November 1993 and Gamsakhurdia was probably murdered on 31 December 1993.

Gamsakhurdia's body was recovered and his death was confirmed on 17 February 1994.

After Gamsakhurdia's death, some Zviadists moved to underground resistance in Western Georgia, especially Mingrelia. Zviadists never created a single party, but some of them joined various political organizations and social movements, while others continued to fight Eduard Shevardnadze's government.

After the civil war, Mingrelia remained a stronghold of the Zviadists. Many Mingrelians were alienated from the government of Eduard Shevardnadze because of the reprisals conducted against the population of the region during the civil war by the paramilitaries supporting Shevardnadze, including Jaba Ioseliani's Mkhedrioni. Shevardnadze and his government, on the other hand, remained suspicious of Mingrelians. Mingrelians did not develop separatist tendencies, but the trauma of the recent conflict distanced them from other Georgians.

After Gamsakhurdia's death, many Zviadists continued their political activities and faced repression and harassment by the authorities. In 1994, several opposition demonstrations were dispersed by the police, and Zviadist political prisoners were subject to torture and violations of due process. In December 1993, the criminal proceedings were initiated against the Zviadist newspapers Iberia-Spektr and Sakartvelos Samreklo, with their publications being halted. Mingrelia was put under the state of emergency in October 1993 and remained so until 5 October 1994, when the Provisional Committee for Emergency Situations in Western Georgia was abolished by Eduard Shevardnadze. In 1996 and 1997, the Zviadists held demonstrations to mark the independence day, but were violently suppressed by the police. In contrast, the demonstration on 31 March 1998 on the independence referendum day, proceeded without any incidents.

In November 1996, Loti Kobalia, the commander of the Zviadist paramilitary forces during the civil war, was sentenced to death for "high treason, banditry, and the commission of premeditated murders". The former parliamentary deputies Jambul Bokuchava, Zviad Dzidziguri, and Nugzar Molodinashvili were also sentenced on similar charges. The defendants argued in the court that they were defending the "lawful state power against its usurpation by Eduard Shevardnadze".

The Presidium of the Georgian Supreme Council, overthrown in 1992, continued to hold meetings abroad and functioned as the government-in-exile. The Supreme Council declared the 1995 elections in Georgia as "null and void". The Zviadist diaspora formed in the Baltic countries, Russia and Finland, with the latter officially granting Zviadists political asylum. However, the Zviadist diaspora did not exercise much power, and they mostly focused on financial support to Zviadist prisoners in Georgia, spread of information about the prisoners to the international human rights organizations, and financial support to Zviadist newspapers.
