Oshkosh Wisconsin 2013 Irish Festival: Please visit the website for actual event time-lines and costs. We are very excited to immediately start the planning for our 5th Anniversary May 31, June 1, and June 2. At different times during the upcoming year, we will be announcing special fundraisers and activities to help build excitement. Please stay in touch. We want to make our 5th Anniversary extra special, but know that it will take a lot of funding. Oshkosh Irish Fest is a 501 (c) 3 non–profit organization. We are completely volunteer run and rely heavily on sponsors and volunteers. If you are interested in being a part of the festival as a donor, sponsor, or volunteer, please let us know.
