ABSTRACT: This article compares the performance of the tourism industry in Northern Ireland and the Republic of Ireland. The analysis shows a strong recent performance in Northern Ireland, but there are a range of performance gaps compared to the Republic. Deepening existing cooperation may have the potential to unlock long-term growth across the island, by leveraging the more developed sector in the Republic, and perhaps benefiting from emerging capacity constraints there. The weaker performance to date in Northern Ireland is in part a reflection of a lower starting point given the legacy of the Troubles, but the North–South gaps continue to widen. A stronger convergence is possible, with significant growth potential for Northern Ireland, through a single tourism offering, and such a single offering could change visitors’ perceptions. However, several policy areas are not devolved and would require changes by the UK government, making the process more complex.
