The Department of Agriculture, Aquaculture and Fisheries is an executive agency of the Government of New Brunswick.

The department was established on March 23, 2000 when Premier Bernard Lord restructured the New Brunswick Cabinet.

The creation of this department was very controversial and marked by protests by both farmers and fishers, though primarily farmers, who felt that the new department would not be specialized to adequately address their issues.

On March 2, 2007, a bill disbanding this department and creating a Department of Agriculture and Aquaculture and a Department of Fisheries received royal assent, the bill was retroactive to October 3, 2006.

When Graham left office, Alward re-merged the departments under the new name Agriculture, Aquaculture and Fisheries.
