Sebastian Alexander Jung (born 22 June 1990) is a German footballer who plays as a right back for Hannover 96 in the Bundesliga.
Jung played his first Bundesliga match for Eintracht Frankfurt, and first fully professional game, on 8 March 2009 in a 0–0 draw against Arminia Bielefeld, as a substitute for Patrick Ochs. On 7 February 2010, he scored his first Bundesliga goal at Signal Iduna Park against Borussia Dortmund. He became a regular in the Frankfurt first team during the 2010–11 season, during which they were surprisingly relegated from the Bundesliga, but was almost ever-present the following season as they bounced back at the first attempt. He extended his contract on 4 April 2013 until 30 June 2015.
He joined VfL Wolfsburg on 22 May 2014 and signed a contract until 30 June 2018. Although he was still under contract with Frankfurt, Wolfsburg could acquire his services by fulfilling a release clause in the amount of €2.5 million. His annual salary at Wolfsburg is believed to be €4 million.
