Gundelsheim (German pronunciation: [ˈɡʊndl̩sˌhaɪ̯m] ⓘ) is a town in the district of Heilbronn in Baden-Württemberg in southern Germany.

It is situated on the right bank of the Neckar, 17 km northwest of Heilbronn.

Pickled gherkin manufacture and wine-growing are the two principal agricultural products, and the Neckarsulm-Gundelsheim Weingärtnergenossenschaft (vintner's co-operative) is reputed to be the oldest in all of Germany.

The most remarkable building in Gundelsheim is Castle Horneck, a former residence of the Teutonic order, now hosting the Transylvanian Museum.
