Harborfest, an annual music festival held the last full weekend of July along the shores of Lake Ontario in Oswego, NY. July 23 – 26, 2026 marks the 37th year that Harborfest will offer free music, entertainment, and programming on three stages in three different venues to upwards of 50,000 people annually.
Over the years, we have featured a great line up of national acts, including Night Ranger, The Family Stone, Blues Traveler, Dennis DeYoung, and many other regional and local performers. Our 2025 plans include another great lineup of headliners, more Jazz & Blues, Arts & Crafts and Commercial Vendors, a Midway, Animal Attractions and much more. Saturday night, thousands will gather to witness the award winning Fireworks Spectacular by Grucci.
We have had success in providing exhibit space to marketing units such as Ford, Geico, Verizon Wireless, the NYS Lottery, Turkey Hill Dairy, Smuckers and many more. If you represent a company that is promoting a product or business we would invite you to be a part of our festival. Please complete and return the Marketing Unit Application, which can be found below, and a Harborfest representative will contact you shortly. Please contact the Membership/Marketing Coordinator if you have any questions about Marketing Units.

The 2026 Marketing Unit application will be posted as soon as it is available.
