Spencerville Summerfest is an annual festival in Spencerville, OH. It is celebrated to honor our local community, businesses and spirit. Spencerville Summerfest began in 1994 to celebrate the sesquicentennial of Spencerville, OH. The first year the local VFW organized the event in conjunction with the Spencerville Invincible Fire Department. The following year a committee took over the planning of this event. The event features a carnival, food vendors, craft shows, car show, community garage sales, parade and fireworks. Join us this year for a great weekend!
