Bäckaby Old Church was a wooden church building in Sweden. The oldest pieces were dated back to the 1320s. The old wooden church was originally in Bäckaby outside Vetlanda before being purchased by a private person and moved to the town park in Jönköping where it was reopened on 31 August 1902. Back in Bäckaby, Bäckaby Old Church had been replaced by the newer Bäckaby Church in 1899.
