The bar was devastated after a police helicopter crashed into its roof killing 10 people in November 2013.
On a busy Friday night the helicopter plunged into the pub killing customers John McGarrigle, Mark O'Prey, Gary Arthur, Colin Gibson, Robert Jenkins, Samuel McGhee and Joe Cusker.
The three police officers on board the helicopter were also killed.
The pub had been closed since that tragic night.
The interior of the old pub remains sealed off but a new bar has been built in what was the adjacent smoking area.
Families of the victims, survivors and members of the emergency services who dealt with the crash on the night were invited to the pub's relaunch last Friday, July 24.
First Minister Nicola Sturgeon attended the opening ceremony and helped to serve the first beer in the new Clutha.
In June Prince Charles visited the new venue.
Owner Alan Crossan told BBC Scotland: "What we are trying to do is bring the Clutha back to Glasgow and give it back to the Glasgow people.
"It was the people who made the Clutha. Not the building or anything like that.
"It was the people - the musicians, the staff, the punters."
Speaking on Radio Scotland's Newsdrive programme, Billy Coyle from the Clutha Trust said: "We've been planning to get the pub opened as soon as possible.”
The Clutha Trust is a charity working to support young people in the aftermath of the crash.
