The Alberta New Democratic Party (NDP) is a social democratic political party that has served as both government and opposition in Alberta. The NDP formed government from 2015-2019 under Premier Rachel Notley, the first time a party other than conservatives governed Alberta in over 40 years. As a social democratic party, the Alberta NDP generally supports stronger public services, worker protections, environmental regulations, and progressive taxation. Currently in opposition, the party provides alternative policy proposals and scrutinizes the governing party's decisions. The Alberta NDP is affiliated with the federal NDP but operates independently on provincial matters.
