Which Countries Celebrate Halloween? The World’s Spookiest Map

Nine days to October 31. Costumes are sold on every continent, but who actually celebrates Halloween? The honest answer is a gradient, from countries where skipping trick-or-treat would disappoint an entire street, to countries where the whole thing happens inside a shopping mall, to a few where the authorities would rather it didn’t happen at all.

The Map: a Holiday in Five Tiers

The deep-orange core is small: the United States, Canada, Ireland and the United Kingdom, the only places where residential trick-or-treating is a true nationwide institution. Around it, a broad adopted belt: Australia and New Zealand (street by street), most of Western and Northern Europe (parties, school events and serious retail, with less door-knocking), and Colombia, Latin America’s genuine October 31 stronghold. The pale tier is the urban-commercial scene: Japan’s costume parades, Seoul’s nightlife, mall Halloween from Manila to Mexico City to São Paulo, a party for adults and retailers more than a children’s ritual.

From Samhain to Suburbia

Halloween’s pedigree is older than almost any national holiday on this map: the Gaelic festival of Samhain marked summer’s end over two millennia ago, when the boundary to the otherworld thinned and bonfires and disguises kept the spirits confused. Christianity overlaid All Hallows’ Eve on the same night; Irish and Scottish emigrants carried the customs to North America in the 19th century, where they fused with candy capitalism into the holiday the world now imports back. Ireland still celebrates hardest at home: Púca Festival and Derry’s Halloween festival (Europe’s largest) claim the origin story explicitly.

Where It’s Frowned Upon, and the Country That Flipped

The purple tier needs precision, because “banned” is usually an overstatement. Iran restricts public and school celebrations as Western cultural imports. Malaysia’s National Fatwa Council has ruled against Muslim participation, institutional discouragement rather than street-level prohibition. Russia’s Orthodox Church and many school authorities condemn it as occult, with local bans but no national law. The most interesting case moved the other way: Saudi Arabia, where Halloween was long effectively prohibited, now hosts costume and horror events inside the state-run Riyadh Season, imported spookiness, on the government’s terms.

The Other Festivals of the Dead

Much of the world doesn’t need Halloween: it already has an older appointment with its dead, and in most of these countries the local festival outranks October 31 completely.

Seen from this table, Halloween’s global spread looks less like a conquest and more like a convergence: nearly every culture already set aside days for the dead. The Irish version just happens to come with better marketing, and candy.
