Cerasuolo is an Italian village, the most populated hamlet (frazione) of Filignano, a municipality in the province of Isernia, Molise. As of 2009 its population was of 151.
During the 20th Century, the municipal population of Filignano has been decreasing due to emigration in Northern Italy and in the United Kingdom. Cerasuolo is, among the 13 municipal villages, the most populated by a community of Italian Scots, children and grandchildren of Filignanese immigrants, returning from Scotland. An event that celebrates this cultural link is, for example, the annual "Scottish Festival Fish & Chips".
