GUI Ulster — Cross-Border Golf Governance
GUI Ulster is the Ulster branch of Golf Ireland, governing amateur golf across nine counties in Ireland's northern province. The branch administers competitions, handicapping, and club affiliations under the World Handicap System across both jurisdictions. Golf Ireland
The Nine Counties of Ulster Golf
Northern Ireland (6 counties): Antrim, Armagh, Down, Fermanagh, Londonderry, Tyrone Republic of Ireland (3 counties): Cavan, Donegal, Monaghan This unique cross-border structure reflects Ulster's historical provincial boundaries, predating the 1921 partition. Golf Ireland's provincial system — Leinster, Munster, Ulster, Connacht — follows Ireland's traditional four provinces rather than political borders. The cross-border nature creates a seamless amateur golf community. Players from Portrush (Northern Ireland) and Donegal (Republic of Ireland) compete together in Ulster championships, inter-club competitions, and provincial events. Handicaps are recognized across both jurisdictions under Golf Ireland's unified system. See our World Handicap System guide.
Ulster Championships and Inter-Club Competitions
GUI Ulster administers provincial qualifying for all AIG Cups & Shields competitions. Ulster clubs compete in Senior Cup, Barton Shield, Jimmy Bruen Shield, Pierce Purcell Shield, and Junior Cup qualifying, with provincial winners advancing to all-Ireland finals. Royal Portrush, Malone, and Donegal Golf Club dominate Ulster's inter-club history. The branch also runs Ulster-specific championships including strokeplay and matchplay events at scratch and handicap levels. Follow results on our live golf scores page.
Ulster Golf Tournaments & Championships
Ulster hosts major amateur and professional tournaments, from The Open Championship at Royal Portrush to provincial amateur events across the region.
The Open Championship at Royal Portrush
The Open Championship returned to Royal Portrush in July 2019 after 68 years. Shane Lowry won by six shots with a final-round 72 in brutal wind and rain on Sunday. Lowry's victory — Ireland's first Open champion since Padraig Harrington in 2008 — came in front of record crowds at Portrush. Portrush returned to the rota just six years later, in July 2025 — Scottie Scheffler's four-round 267 (17-under) won by four shots over Harris English, the course's third Open and the first time it had hosted twice within a decade.

North of Ireland Amateur Championship
The North of Ireland Amateur Championship at Royal Portrush is one of Irish golf's four provincial championships, held 13–15 May in 2026, won by Dylan Keating. The strokeplay qualifying and matchplay knockout format attracts Ireland's best amateurs. Past champions include Rory McIlroy, Graeme McDowell, Darren Clarke, and other professionals who learned their competitive golf in Ulster events.
NI Open
The NI Open is Northern Ireland's professional golf championship, part of the Challenge Tour (European Tour's developmental tour). The event rotates among Northern Ireland courses, providing local professionals with opportunities to compete at home.
Ulster Scratch Cups
Ulster's scratch cup circuit includes events at Royal Portrush, Portstewart, Royal County Down, and Donegal Golf Club. These 36-hole strokeplay competitions attract Ulster's best amateurs plus visitors from across Ireland. Royal Portrush Scratch Cups: the Mabel Harrison Scratch Cup (Valley Course, women's event) and Zara Bolton Scratch Cup (Dunluce Course, women's event) are among Ireland's most prestigious women's amateur competitions. Donegal Scratch Cup: annual event at Donegal Golf Club, attracting strong fields to the northwest coast. See the Irish golf tournaments calendar.
Golf Tourism in Ulster
Ulster's golf tourism centers on the Causeway Coast — the coastal stretch from Portrush to Ballycastle featuring Royal Portrush, Portstewart, and Castlerock. Golf breaks typically combine championship courses with sightseeing at the Giant's Causeway, Carrick-a-Rede rope bridge, and Bushmills Distillery. See our Irish golf courses guide.
Causeway Coast Golf Trail
The Causeway Coast offers concentrated access to championship links:
- Royal Portrush (Dunluce & Valley)
- Portstewart (Strand, Old, Riverside)
- Castlerock Golf Club
- Ballycastle Golf Club
Many golf tourists base in Portrush or nearby Bushmills, playing different courses daily.
Donegal Golf Circuit
County Donegal features multiple championship courses in spectacular settings:
- Donegal Golf Club (Murvagh)
- Ballyliffin Golf Club (Old Links & Glashedy)
- Rosapenna Golf Resort
- Portsalon Golf Club
- Narin & Portnoo Golf Club
Donegal's remote location means fewer crowds than the Causeway Coast.
Belfast & County Down
Belfast-based golf breaks combine parkland courses (Malone, Royal Belfast) with links at Royal County Down in Newcastle. The Mourne Mountains provide scenic backdrops and outdoor activities beyond golf.
Ryder Cup 2027 & Irish Golf
Ireland hosts the 2027 Ryder Cup at Adare Manor in County Limerick (Munster). While outside Ulster, the event represents a landmark for Irish golf and will attract global attention to Ireland's courses and golf tourism offerings. Northern Ireland's golf infrastructure — demonstrated through The Open 2019 at Portrush — positions the region for future major championships. The success of Portrush has elevated Northern Ireland's profile in championship golf alongside Scotland and England's traditional venues. Many golf tourists visiting Ireland for the Ryder Cup will extend trips to play Ulster's championship courses, particularly Royal Portrush and Royal County Down. Check the latest golf betting odds.
