A Bachelor of Science in Agriculture (BSAg) or a Bachelor of Agriculture (BAg) is an undergraduate academic degree awarded by tertiary faculty of agriculture. The program is typically four years of study at postsecondary level.

In Canada, the bachelor's degree in agriculture differs from a bachelor of science degree in that the courses focus on agriculture: for example, the student will study agricultural economics rather than economics. Like engineering or forestry, agricultural science courses are infused with practicality.

In China, the Bachelor of Agriculture is an independent degree and one of the thirteen statutory types of bachelor's degrees. It is awarded to students who have completed an undergraduate program majoring plant production, nature conservation and environmental ecology, animal production, veterinary medicine, forestry, aquaculture and fishery, or grassland science.
