Jens Georg Spahn (born 16 May 1980) is a German politician of the Christian Democratic Union (CDU) who has been a member of the lower house of the federal parliament, the Bundestag (German: Mitglied des Deutschen Bundestages, MdB), for Steinfurt I – Borken I since 2002. Since 2025, he has been leading the joint CDU/CSU (Union) parliamentary group in the 21st Bundestag, making him the majority leader. He served as Federal Minister of Health in the fourth cabinet of Chancellor Angela Merkel from 2018 to 2021, including during the COVID-19 pandemic in Germany.

At the time of his first election in 2002, Spahn – at age 22 – was the youngest member of the CDU in the German parliament. He has since been one of the main sponsors of pension reform in Germany. He was a member of the Committee of Health of the 17th Bundestag and the CDU/CSU parliamentary group's spokesperson on health.

When Chancellor Angela Merkel stated her intention not to seek re-election for the CDU party leadership in 2018, Spahn announced his intention to stand for election as her successor in December 2018. He was eliminated in the first round of voting; the position instead went to Annegret Kramp-Karrenbauer. Following Kramp-Karrenbauer's decision to resign in February 2020, he announced that he would not run for the party's leadership but instead endorse candidate Armin Laschet. His alliance with Laschet proved successful, as his ally became CDU party leader on 16 January 2021 and candidate for chancellor of the CDU/CSU party alliance on 19 April 2021.

Spahn was born on 16 May 1980 in Ahaus, North Rhine-Westphalia. He grew up with his two younger siblings in the village of Ottenstein in the north of Westmünsterland. Spahn graduated in 1999 from the Episcopal Canisius school in Ahaus. In 2001 he completed an apprenticeship as a bank teller at the Westdeutsche Landesbank, and worked in that profession until 2002. In 2003, Spahn began studying political science at the University of Hagen. In 2008, he obtained a bachelor's degree, followed by a master's degree in the same field in 2017.

Spahn became a member of the Junge Union Deutschlands (JU) in 1995, aged 15. He went on to join the CDU in 1997. He was the chair of the Borken district JU from 1999 to 2006. In 2005, he also took up the chair of the Borken district CDU, which numbers 6,500 members.

In December 2014 Spahn unexpectedly stood for a place on the CDU's ruling council against health minister Hermann Gröhe, in a contest widely seen as crystallizing the generational tensions within the party. His election bid was backed by the then 72-year-old finance minister, Wolfgang Schäuble. Shortly before the vote at the annual CDU party conference, Gröhe withdrew his candidacy and Spahn was elected.

He has been mentioned as a possible replacement for Angela Merkel as Chancellor, and stood in the CDU leadership campaign in 2018 after Merkel announced that she would not seek re-election as party leader. However, the 157 votes he secured, despite being more than expected, was insufficient for him to qualify for the second round of voting, which was won by Annegret Kramp-Karrenbauer.

Spahn has been a member of the Ahaus City Council since 1999.
