UKIP’s National Spring Conference 2014 is expected to attract 1,000 delegates when it takes place from 28 February to 1 March 2014.
UKIP were last at the RICC in September 2010 for its annual conference.
Steve Crowther, chairman of UKIP and organiser of the 2014 Spring Conference said: "Following the close of our last conference at the RICC, we received a large number of compliments about how good the venue was and how polite and cheerful the staff were.
"The service we received during the planning and staging of our conference was superb with excellent feedback on the standard of catering. There was particular praise for the gala dinner."
Julien Parrott, chairman of Torbay Council and UKIP councillor, said: "We are always thrilled to welcome large, high profile events such as this and in particular the return of this one. The obvious benefits, including the expected media attention, are invaluable to the RICC and the Bay. There is also no better endorsement for a job well done than the return of a conference."
