An election was held for the leadership of the Meretz party on 22 March 2018. It saw the election of Tamar Zandberg.
The vote was open to party members. Party membership increased by 12,000, to roughly 30,000, ahead of the vote. Outgoing leader Galon wanted the election to use an open primary-style system in which any Israeli citizen could vote, regardless of party registration. The party wound up instead adopting a compromise presented by Tamar Zandberg, which saw the party allow anyone to register as a party member up to a month before the leadership election and the party's slate-selection primary, and be allowed to participate in those elections.
The party reported that 53.69% of eligible voters participated in the election. The party reported that 130 polling stations across Israel were utilized for the vote.
