The premier of New Brunswick (French: premier ministre du Nouveau-Brunswick (masculine) or première ministre du Nouveau-Brunswick (feminine)) is the first minister and head of government for the Canadian province of New Brunswick.

They are normally the leader of the party or coalition with the most seats in the Legislative Assembly of New Brunswick.

The premier is styled Honourable but is not a member of the privy council so this title is only for the duration of their term of office.

Since the 1840s responsible government has been in place and the position of premier has been formalized.

After winning a majority in the 2024 general election, she became the first female premier in New Brunswick.
