Hamburg is an unincorporated community in Ray Township, Franklin County, Indiana.
Hamburg was platted in 1864 by Wesley Martin.[2] It was named after Hamburg, in Germany.[3]
Hamburg was once a thriving Catholic community. St. Ann's Catholic Church was founded in Hamburg in 1869. The Church closed its doors in 2013 merging with Holy Family Parish in Oldenburg.[4] [5]
A post office was established at Hamburg in 1867, and remained in operation until it was discontinued in 1929.[6]
