Josephine Fock (born 5 September 1965) is a Danish politician, who was a member of the Folketing for The Alternative from 2015 to 2018. She was the leader of the party from 1 February to 14 November 2020 after Uffe Elbæk resigned.
On 16 December 2019 the leader of the Alternative, Uffe Elbæk, announced that he would like to pass on the leadership. On 1 February 2020 Fock became the party's new leader. A month later, on 9 March, Uffe Elbæk, Susanne Zimmer, Sikandar Siddique and Rasmus Nordqvist left the party, with Elbæk stating that he "could no longer recognize the party that he founded" under Fock's leadership. This left the party with only one member in parliament: Torsten Gejl. On 14 November 2020 Fock resigned as the party's leader, leaving Gejl as the ad interim leader until 7 February 2021 where Franciska Rosenkilde became the new official leader.[2][3][4][5]
