Hardinxveld-Giessendam (Dutch pronunciation: [ˈɦɑrdɪŋksfɛlt ˌxisə(n)ˈdɑm] ⓘ)[a] is a municipality in the western Netherlands, in the province of South Holland.

The town's economy is for a large part dependent on ship building (e.g. Damen Shipyards Group) and general contracting.

In recent years, the municipality had serious fiscal problems, resulting in direct oversight by the Province for a period of time.

During that research in Hardinxveld-Giessendam, some archeological items were found, including a 7500-year-old skeleton of a woman, now named "Trijntje".

Since December 2003, the reconstructed corpse has been added to the collection of the Rijksmuseum van Oudheden (National Museum of Antiquities) in Leiden.
