UKIP's conference will be held on 2-4 September and is anticipated to attract 700 delegates.
The event will comprise conference sessions, social events and dinners.
UKIP administration manager David Challice said: "The Riviera International Conference Centre is perfect for our conference and media needs and there is plenty of local accommodation near the centre that can host our delegates, visitors and the media."
Riviera International Conference Centre managing director Barry Cole said the venue and destination would benefit greatly from the focus that would be put on the conference.
Last year's UKIP conference was held in Southport.
