Zack Polanski (born David Paulden; 2 November 1982) is a British politician who has been the Leader of the Green Party of England and Wales since September 2025. He has been a member of the London Assembly (AM) since May 2021. Polanski was the Deputy Leader of the Greens from 2022 to 2025. After being elected as party leader, the party saw a massive increase in membership.

Polanski was born on 2 November 1982 in Salford, Greater Manchester, where he also grew up.

Polanski has said his political views are eco-populist. Under his leadership, the Greens have made some improvements, including Hannah Spencer's victory in the 2026 Gorton and Denton by-election.

Polanski said that he wants to run in the next general election in a constituency near his home in North London.

On 3 September 2026, Polanski announced his plans to run in the Holborn and St Pancras by-election after former Prime Minister, Sir Keir Starmer, resigned his seat. He lost the election on 8 October to Labour candidate Sagal Abdi-Wali.

Polanski is Jewish, gay and vegan.
