Northern Ireland Festivals & Events

Northern Ireland has a habit of throwing itself into celebration with a commitment that can seem disproportionate to its size. A population of under two million people supports an annual calendar dense with festivals — music, food, literature, maritime heritage, comedy, film, and at least one event involving competitive sheep shearing. Some of these draw international crowds. Others are known only to the locals and are better for it.

What follows is a month-by-month guide to the events worth planning around. Dates shift from year to year, so check specific festival websites for the current programme, but the broad calendar has been consistent for years.

January and February

Belfast International Arts Festival (Late October–November, Residual Events into January)

The tail end of Belfast’s major arts festival sometimes carries programming into the new year — fringe events, exhibitions, and film screenings that keep the city’s cultural calendar from going entirely dormant in deep winter.

Six Nations Rugby (February–March)

Not a festival in the traditional sense, but Belfast on a Six Nations weekend has a particular electric atmosphere. Ireland plays as a unified team — one of the few major sports where the border disappears entirely — and the pubs fill early. Watching a match in the best pubs in Northern Ireland is an experience in collective emotion that no concert can quite match.

March

St Patrick’s Day (17 March)

The obvious one. Belfast’s St Patrick’s Day celebrations have grown enormously — a multi-day festival now, with a parade through the city centre, live music, markets, and community events. Downpatrick, where St Patrick is traditionally buried, holds its own celebrations with a particular historical weight. Smaller towns across Northern Ireland hold local parades and céilí dances. The atmosphere is warm, inclusive, and substantially less commercialised than some international St Patrick’s events.

Belfast Nashville Songwriters Festival (March)

A quieter affair that reflects Belfast’s deep connection with country and Americana music. Songwriters from Nashville and across Ireland perform in intimate venues, sharing stories between songs. The city’s musical roots run deep — see our Northern Ireland music scene guide for context.

April and May

Cathedral Quarter Arts Festival (Late April–May)

Belfast’s Cathedral Quarter — cobbled streets, converted warehouses, and independent bars — hosts this multi-disciplinary arts festival every spring. Theatre, comedy, visual art, spoken word, and music in venues that range from proper theatres to car parks. It has a scrappy, ambitious energy that bigger festivals sometimes lose.

Balmoral Show (May)

Northern Ireland’s largest agricultural event, held at Balmoral Park south of Belfast. Livestock judging, equestrian events, food halls, farming machinery, and a cross-section of rural life that visitors rarely see. If you want to understand the farming communities that shape most of Northern Ireland’s landscape, spend a day here. Children love it. Adults pretend they’re there for the children.

North West 200 (May)

One of the world’s great road racing events, and the largest outdoor sporting event in Ireland. Motorcycles race on a triangular circuit of public roads between Portstewart, Coleraine, and Portrush at speeds exceeding 200 mph. The atmosphere along the course — families in deckchairs, the smell of racing fuel, the visceral noise — is unlike anything else. Road racing is part of Northern Ireland’s cultural DNA, and the North West 200 is its purest expression.

June

Dalriada Festival, Glenarm (June–July)

Held in the grounds of Glenarm Castle on the Antrim coast, this festival celebrates local food, crafts, and highland games. Tug-of-war, sheep shearing, artisan food stalls, and live music in a castle setting overlooking the sea. It captures something essential about the Glens of Antrim — community, landscape, and excellent baking.

Rathlin Sound Maritime Festival (Late May–June)

A celebration of the maritime heritage of Rathlin Island and the surrounding coast. Boat trips, guided walks, talks on marine wildlife, and traditional music. Our Rathlin Island guide covers the island itself — the festival adds another reason to make the crossing.

July and August

Belfast International Tattoo (July)

Military bands, pipe bands, and musical displays at the Balmoral Showgrounds. Spectacular choreography and sound on a grand scale.

Stendhal Festival (July–August)

An independent music and arts festival held in the beautiful Roe Valley, outside Limavady in County Derry. Small enough to feel intimate, large enough to attract serious artists. Camping, art installations, workshops, and a commitment to sustainability that sets it apart from larger commercial festivals. The setting — wooded river valley with the Binevenagh cliffs nearby — is genuinely stunning.

Féile an Phobail (August)

The West Belfast Festival, and one of the largest community arts festivals in Europe. Born in 1988 during the Troubles as a positive expression of community identity, Féile has grown into a major cultural event — music, drama, debate, comedy, exhibitions, and talks. It offers a perspective on Belfast’s history and present that tourist brochures rarely capture. Pair it with our Troubles history guide for deeper context.

Auld Lammas Fair, Ballycastle (Late August)

Ireland’s oldest traditional market fair, held on the last Monday and Tuesday of August in Ballycastle. It has been running since 1606. Streets fill with market stalls, amusements, horse trading, and two traditional sweets — dulse (dried seaweed) and yellowman (a hard honeycomb toffee). The song “The Ould Lammas Fair” is known by every schoolchild in Northern Ireland. Visit Ballycastle and you’ll hear it played in every pub.

September and October

Culture Night Belfast (September)

One night a year, Belfast opens its doors — literally. Museums, galleries, studios, churches, government buildings, and private collections open for free, with performances, installations, and walking tours across the city. It draws tens of thousands of people onto the streets in a celebration of curiosity. Similar Culture Night events run in Derry~Londonderry and other towns.

Belfast International Arts Festival (October–November)

The main event in Northern Ireland’s cultural calendar. Three weeks of theatre, dance, music, visual art, film, and literature featuring international and local artists. Venues range from the Grand Opera House to pop-up spaces in industrial buildings. The programming is ambitious and consistently strong.

Hillsborough International Oyster Festival (September)

The pretty Georgian village of Hillsborough hosts this festival celebrating oysters, local food, and live music. Oyster-shucking competitions, tastings, craft markets, and a convivial atmosphere. Northern Ireland’s food scene — explored further in our food guide — is well represented here.

November and December

Derry Halloween (31 October–Early November)

The undisputed highlight. Derry~Londonderry’s Halloween celebrations are widely regarded as the best in the world — and that’s not local hyperbole. The city within the walls transforms into a vast, immersive theatrical experience. Tens of thousands of people in costume fill the streets. The Return of the Ancients parade features enormous illuminated puppets and performers. Fireworks light up the River Foyle. The atmosphere is extraordinary — genuinely eerie, joyful, and communal. Plan well ahead; accommodation books out months in advance. Our Derry~Londonderry city guide has more on the city itself.

Belfast Christmas Market (November–December)

Belfast City Hall’s grounds fill with wooden chalets selling crafts, food, and hot drinks. Continental and local traders sit side by side. The mulled wine flows freely. It runs from mid-November through late December and is the city’s primary festive gathering point.

Enchanted Winter Garden, Antrim Castle Gardens (November–January)

An illuminated trail through the beautiful Antrim Castle Gardens. Light installations, music, and festive food. A winter highlight for families.

Planning Around Festivals

Northern Ireland’s compact size means you can reach any festival from any base within a couple of hours by car. Belfast is the natural hub, but Derry~Londonderry makes an excellent base for north and northwest events. For travel logistics, see our complete guide to Northern Ireland.

Accommodation fills quickly during major events — especially Derry Halloween, the North West 200, and the Auld Lammas Fair. Book early. And bring a waterproof jacket to every outdoor event without exception. The weather here has no respect for festival programmes.
