Gundelsheim is a town in the district of Heilbronn, Baden-Württemberg, Germany. It is situated on the right bank of the Neckar, 17 km northwest of Heilbronn. The town centre retains its narrow mediaeval street plan, as well as much of its mediaeval timber architecture. Pickled gherkin manufacture and wine-growing are the two principal agricultural products, and the Neckarsulm-Gundelshem Weingaertnergenossenschaft (vintner's co-operative) is reputed to be the oldest in all of Germany.
