Announced at this year’s event in Plymouth this week, the 2018 convention will run from February 7-9.
The event will comprise three days of debates, addresses from keynote speakers and networking opportunities in and around Cardiff.
There will also be a B2B workshop and a black-tie gala dinner, at which the winners of the association’s annual Awards for Excellence will be announced.
Supported by Visit Wales, a series of fam trips will showcase the country’s tourism offering, including a visit to North Wales.
UKinbound’s chief executive officer, Deirdre Wells OBE, said: “We are delighted to announce Cardiff as the host city of our Annual Convention next year.
“Our ambition is to support inbound tourism business across the UK and tourism in Wales is going from strength to strength.”
Wells continued: “The city has an exceptional tourism offering, home to superb shopping, innovative architecture, historic buildings, and more urban green spaces than any other city in the UK.
“As the hosts of The UEFA Champions League Final 2017, Cardiff is likely to attract more inbound visitors and we look forward to further raising the profile of Europe’s youngest capital city.”
Welsh government economy secretary, Ken Skates, said: “Tourism in Wales is in a strong position and the overseas figures for the first nine months of 2016 show that Wales saw a 12% increase in the number of visitors and a 9% increase in spend.
“We look forward to working with UKinbound to further increase Wales’ share of overseas visitors coming to the UK.”
