(For other uses, see Traveler (disambiguation).) Irish Travellers (Irish: an lucht siúil) also called pavees, or pejoratively referred to as tinkers and gypsies, are a traditionally itinerant ethnic group who maintain a set of traditions. Although predominantly English speaking, some also use Shelta and other similar cants. They live mostly in Ireland as well as having large numbers in the United Kingdom and in the United States. Their origin is disputed.
