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 Back in Bäckaby, Bäckaby Old Church had been replaced by the newer Bäckaby Church in 1899.
