As of the most recent provincial election, the Alberta New Democratic Party (NDP) holds 24 seats in the 87-member Legislative Assembly of Alberta. This makes the NDP the Official Opposition to the governing United Conservative Party (UCP).
The NDP leader serves as Leader of the Opposition, tasked with holding the government accountable, proposing alternatives, and chairing opposition caucus meetings. The party's critics shadow key ministries such as Health, Education, Energy, and Labour.
The NDP formed government from 2015–2019 under Premier Rachel Notley, winning 54 seats. The 2019 and 2023 elections saw a return to opposition status.
