Ballaghaderreen () is a town in County Roscommon, Ireland. It was part of County Mayo prior to 1898. It is located just off the N5 National primary road. The population was 1,808 in the 2016 census. History As of 1837, the town was recorded as having 1147 inhabitants in about 200 houses and as "rising in importance" as a post-town, being on the (then) new mail coach road from Ballina to Longford. As of the mid-19th century, markets were held on Fridays, with seven fairs held throughout the year. A court-house, market house and an infantry barracks to accommodate 94 persons had all been established by that time. In 1860, Ballaghaderreen Cathedral was dedicated as the cathedral for the Roman Catholic Diocese of Achonry. In March 2017, Ballaghaderreen became an Emergency Reception and Orientation Centre (EROC) for hundreds of refugees from the Syrian Civil War. In April 2018, the community was honoured with a People of the Year Award for welcoming the refugees into the community. Governance Ballaghadereen is part of the Barony of Costello and in the parish of Kilcoleman. Ballaghaderreen has been part of County Roscommon since 1898 when the town and parish of Ballaghaderreen and Edmondstown were transferred from County Mayo under the Local Government Act 1898.
