Rags are student-run charitable fundraising organisations that are widespread in the United Kingdom and Ireland. Some are run as student societies whilst others sit with campaigns within their student unions. Most universities in the UK and Ireland, as well as some in the Netherlands and the Commonwealth countries of South Africa and Singapore have a Rag. In some universities Rags are known as Charities Campaigns, Charity Appeals, Charity Committees, Jool or Karnivals, but they all share many attributes.
