On 2 November 2020, a series of shootings took place in Vienna, Austria a few hours before the city was scheduled to enter a lockdown as a result of the COVID-19 pandemic. A lone gunman started shooting in the busy city centre, killing four civilians and injuring 23 others, seven critically, including a police officer. The attacker was killed by police and was later identified as an ISIL sympathizer. Officials said that the attack was an incident of Islamist terrorism.

Before the attack, at around 16:00, Kujtim Fejzulai uploaded a confession video on his social media before making a call to the restaurant: Le Salzgries. At 17:44, Fejzulai left his apartment to walk to the city center. He uploaded two more photos on his social media at 19:17 and 19:26 respectively. Fejzulai arrived at Schwedenplatz at 19:31. From there, he walked to the Le Salzgries restaurant. He walked around and passed by it two more times until he realized it was closed. Fejzulai changed course and travelled to Seitenstettengasse. He briefly walked towards the St. Rupert's Church before walking south towards a hotel building to prepare for the shooting. When the shooting started, he was armed with a rifle, a handgun, and a machete and was wearing a fake explosive belt that was underneath his jacket.

The first shots were fired at 19:59:20, when Fejzulai fired at a group of people to his right. The group were chatting at the top of the Jerusalem-Stairs. Fejzulai fired two lethal shots at a 21-year-old man from that group. Fejzulai ran north up Desider-Friedmann-Square and opened fire on a couple who were walking to his left, injuring one. Fejzulai continued north to the St. Rupert's Church and opened fire to his right on a beer garden located at the corner of Judengasse and the church. He wounded eight people with gunfire. After shooting at the beer garden, Fejzulai turned to his left and opened fire at the terrace of the Salzamt restaurant, fatally shooting a 25-year-old woman. The shooter ran north to reach the stairs to the courtyard of St. Rupert's Church, only to realize the gate was locked. He retreated to the entrance of a closed restaurant to reload his rifle. Fejzulai ran towards Seitenstettengasse while firing more shots at people, hitting no one. Once at Seitenstettengasse, the shooter encountered a 44-year-old woman as he was walking down the alley. He opened fire on her with his rifle, hitting her with three shots and causing her to collapse. The shooter continued walking until he reached the terrace of the Krah Krah restaurant, which was located on Rabensteig. He opened fire on the patrons and wounded seven of them. The shooter turned around and ran back to the woman he had shot in Seitenstettengasse. He pulled out a Tokarev handgun from his waistband and shot at her twice, killing her. The shooter reloaded his rifle and ran to the Kaktus bar. He fired a single shot from his rifle at the building, hitting no one. The shooter ran back to Rabensteig and turned to his left to go north. The shooter reached the corner of Franz-Josefs-Kai and Rabensteig, and walked to his right. A restaurant owner was about to lock his restaurant's entrance. The shooter fired at him and injured him lethally. One of the restaurant's employees was also injured. The shooter ran east, then north, up through a pocket park area just southwest of the tram tracks. He reloaded his rifle. At 20:03:45, two police officers in a police car confronted him. He fired at the officers, hitting one in the thigh. Fejzulai ran away down Franz-Josefs-Kai towards the courtyard of St. Rupert's Church. While he was running, a bystander threw glass objects at him. He even briefly stopped to shoot at a rental car, hitting no one. The attack ended when the gunman was shot by police at 20:08:48 at the courtyard of St. Rupert's Church. The police shot him from 50 meters distance. The shooter fired 80 rounds in total, firing 78 from the Zastava rifle and 2 from the handgun. Bullet holes were found on a tanker, making police believe Fejzulai intended to cause an explosion mid-shooting.

The shooting took place four hours before the midnight start of a nationwide lockdown as new COVID-19 restrictions were due to come into force in Austria, including a 20:00 to 06:00 curfew. Crowds in bars and restaurants were enjoying a last evening out before the lockdown began.

Four people were killed by the attacker: they were a 39-year-old Austrian man, a 24-year-old German woman, a 44-year-old Austrian woman, and a 21-year-old Austrian man originally from North Macedonia. The attacker was also shot dead by the police at the scene.

Twenty-three other people were wounded with gunshot and stab wounds; thirteen citizens from Austria, four from Germany, two from Slovakia, and one each from Afghanistan, Bosnia and Herzegovina, China, and Luxembourg. Seven suffered life-threatening injuries. Among the wounded was a 28-year-old police officer who was shot and critically injured while responding to the attack. The wounded officer and an elderly woman were saved by a Palestinian and two Turkish-Austrian men, who carried them away from the attacker to ambulances. After confronting the attacker, one of the Turkish-Austrians was shot and wounded. The three men were praised for their actions.

Videos of the shooting surfaced, including one of the attacker shooting a civilian first with a rifle and then up close with a handgun. The police asked that witnesses not post videos and photographs on social media, but rather submit them to the authorities. As a result, the police received a large number of videos from the public following the attack, and an investigation team examined them for evidence.

On the morning of 3 November, searches of apartments linked with the perpetrator took place, and in his home they found a stockpile of ammunition. Austrian authorities said at 01:00 that at least one gunman remained on the run, but that afternoon Minister of the Interior Karl Nehammer said there was no indication of additional attackers. Officials stated that the attack was an act of Islamic terrorism.
