Short answer
Whole wheat is wheat whose bran, germ, and endosperm are retained in the relevant whole-grain proportions. Whole grain is the broader category: it can be wheat, oats, brown rice, or another grain with those kernel components. On packaged foods, the presence of a whole-grain ingredient does not by itself tell you that every grain ingredient is whole. 1 2
Whole wheat is a wheat-specific kind of whole grain ingredient; whole grain also includes other grains that retain the kernel components in their original proportions.

What each thing is
Whole wheat. Whole wheat is wheat that retains the bran, germ, and endosperm in approximately their original proportions. The term identifies a specific whole-grain ingredient; a finished food may also contain other ingredients. 1 2
Whole grain. Whole grain is the broader category of grain ingredients that retain the bran, germ, and endosperm in approximately their original proportions, whether the grain is wheat, oats, barley, or another cereal. 1 2
Key differences
Whole wheat is a wheat-specific whole-grain ingredient. Whole grain includes wheat and other grains when bran, germ, and endosperm are retained in their original proportions. Finished foods may mix whole and refined ingredients. 1 2
How to tell them apart
Read the grain ingredients rather than treating a front-of-package phrase as a complete formula. ‘Whole wheat’ identifies wheat in whole-grain form; ‘whole grain’ may refer to wheat or another grain. Check the full ingredient list and any stated percentage if you need to know how much of a finished food is whole grain. 2
Where they overlap
As an ingredient, whole wheat is one kind of whole grain. A multigrain bread might contain whole wheat alongside whole oats, and it might also contain refined flour. The category relationship between ingredients is clear even when a finished product combines whole and refined grains. 1 2
Edge cases
A product can mention a whole grain while also containing refined grain ingredients. Different US labeling programs use different criteria for whole-grain claims, so the phrase on the front does not automatically mean the food is made entirely from whole grains. The ingredient list provides a more specific starting point. 1
Why the distinction exists
This distinction exists because ‘whole grain’ is a category defined by the inclusion of all kernel parts—bran, germ, and endosperm—regardless of grain type, while ‘whole wheat’ is restricted to wheat. Labeling reflects both ingredient identity and regulatory standards. 1 2
Common misconceptions
A common misconception is that ‘whole wheat’ and ‘whole grain’ name competing ingredients. Whole wheat is a type of whole grain, not its opposite. A second mistake is to assume that one whole-grain ingredient makes every grain ingredient in a finished food whole. 2
Examples
A shopper sees one loaf listing whole-wheat flour first and another listing whole oats along with refined wheat flour. Both contain a whole-grain ingredient, but only the first example identifies wheat in whole form as the leading grain ingredient. The full lists tell more than the front labels alone. 2
