The place name is Welsh, but the place is not in Wales. Y Wladfa (Welsh for 'The Colony'); sometimes also known as Y Wladychfa Gymreig ('The Welsh Settlement') was a partly successful Welsh settlement in Argentina, which began in 1865 and occurred mainly along the coast of Chubut Province in Patagonia.

In the 19th and early 20th century the Argentine government encouraged emigration from Europe to populate the country outside the Buenos Aires region. Between 1856 and 1875, 34 settlements of immigrants of various nationalities were established in Santa Fe and Entre Ríos. In addition to the main colony in Chubut, a smaller colony was set up in Santa Fe by 44 Welsh people who left Chubut, and another group settled at Coronel Suárez in southern Buenos Aires Province.

The Welsh-Argentine community is centred on Gaiman, Trelew (Welsh for 'Lewis town') and Trevelin (from Trefelin, Welsh for 'mill town'). Chubut estimates the number of Patagonian Welsh speakers to be about 1,500, while other estimates put the number at 5,000.
