Ehud (Udi) Goldwasser (Ehud Ben Malka Goldwasser) (Hebrew: אהוד גולדווסר‎; 18 July 1975 - circa July 12, 2006) was an Israeli soldier who was captured in Israel by Hezbollah along with Eldad Regev on 12 July 2006, sparking the 2006 Israel-Lebanon conflict. His rank was Sergeant Major.

On July 16, 2008, the bodies of Goldwasser and Regev were returned to Israel in an Israeli-Hezbollah prisoner swap. An examination of the bodies determined that the two reservists were probably killed during the initial attack.

Prior to his capture at Israel's border with Lebanon, Ehud "Udi" Goldwasser lived in Nahariya. He worked at Technion, the Israeli Institute of Technology, from which he earned a degree in aerospace engineering studies. As a teenager, Udi lived in South Africa with his parents, Shlomo and Mickey, and two younger brothers. He was married to Karnit. Udi was interested in environmental conservation, motorcycles, sailing and photography.
