Belfast Visitor and Convention Bureau (BVCB) beat London in a competitive pitch to clinch the major event.
The main conference will be hosted at the Hastings Europa Hotel and a gala dinner will take place at Titanic Belfast.
The Belfast bid was supported by Tourism Ireland. Chief Executive, Niall Gibbons, said: "The Society of Editors is a hugely influential group which can help us greatly in publicising the new, vibrant Belfast and Northern Ireland in overseas tourism markets and highlight the wealth of things to see and do on a holiday here.
"The decision to choose Belfast over other UK cities confirms that we can compete successfully against many of the most popular conference destinations. Delegates will have the opportunity to see the exciting transformation the city has undergone since their last visit over a decade ago, especially with new attractions including Titanic Belfast."
Society of Editors executive director, Bob Satchwell, said: "Belfast is an exciting, modern city with a colourful and unmatched history full of names that filled news bulletins for years. Many of those attending the conference will have cut their journalistic teeth reporting on the troubles and will be keen to re-visit a changed city. Belfast is also renowned for its friendliness so we know we can be sure of a warm welcome."
The Society of Editors’ 400 members represent editors, managing editors and deputy editors in national, regional and local newspapers, magazines, radio, television and new media, as well as media lawyers and academics in journalism education.
