The Baz Luhrmann-directed movie was set to arrive on December 25 in the US and a day later in the UK, but it will now not hit cinemas until summer 2013.
Dan Fellman, President of Domestic Distribution at Warner Bros, explained in a statement: "Based on what we've seen, Baz Luhrmann's incredible work is all we anticipated and so much more.
"It truly brings Fitzgerald's American classic to life in a completely immersive, visually stunning and exciting way. We think moviegoers of all ages are going to embrace it, and it makes sense to ensure this unique film reaches the largest audience possible."
The Great Gatsby is a film adaptation of F Scott Fitzgerald's classic novel of the same name.
It stars Leonardo DiCaprio, Tobey Maguire, Carey Mulligan, Isla Fisher and Joel Edgerton.
"Baz is known for being innovative, but with this film he has done something completely unexpected - making it in 3D - while capturing the emotion, the intimacy, the power and the spectacle of the time," added the Warner Bros' President of International Distribution Veronika Kwan Vandenberg.
"The responses we've had to some of the early sneak peeks have been phenomenal, and we think The Great Gatsby will be the perfect summer movie around the world."
