General elections for Alberta's Legislative Assembly will be held on May 29th. The incumbent United Conservative Party under Danielle Smith will be seeking their second term, while their main challengers are the New Democratic Party under Rachel Notley, who held government between 2015 and 2019. Polls show a tight race, with different pollsters showing different parties in the lead.

In this first-past-the-post election, no party outside these two is expected to win any seats, although one UCP candidate will not be allowed in the party caucus due to offensive remarks (although she remains on the ballot with her affiliation), creating a possibility that both major parties end up tied at 43 seats won.
