Ehud "Udi" Goldwasser (Hebrew: אהוד גולדווסר; 18 July 1975 – 12 July 2006) was an Israeli soldier who was abducted in Israel by Hezbollah along with Eldad Regev on 12 July 2006, sparking the 2006 Lebanon War. His rank was First Sergeant.
On 16 July 2008, the bodies of Goldwasser and Regev were returned to Israel in the 2008 Israel–Hezbollah prisoner exchange. Israeli officials claimed an examination of the bodies determined that the two reservists were killed during the ambush. A Lebanese minister claimed the soldiers were killed during the Israeli bombing.
Prior to his abduction at Israel's border with Lebanon, Ehud "Udi" Goldwasser lived in Nahariya. He was a graduate student at the Technion, the Israeli Institute of Technology, from which he had earlier earned an undergraduate degree in environmental engineering.
As a teenager, he lived in South Africa with his parents, Shlomo and Mickey, and two younger brothers. In 2005, he married Karnit, who would later campaign globally for his release. He was interested in environmental conservation, motorcycles, sailing and photography.
According to the United Nations, the fighting began at around 9 AM when Hezbollah launched rockets on Israeli military positions along the Lebanese border, apparently as a diversion. A force then attacked two armored IDF Humvees patrolling the border near the Israeli village of Zar'it with anti-tank rockets, and abducted the two soldiers. An Israeli Merkava Mk. II tank was damaged by a 200 kg improvised explosive device, while attempting to give pursuit, killing all four crewmembers.
