葛子为一种玉米磨制成大约为1毫米至2毫米粒径的食品，用于煮粥。常见于中国东北南部和美国南方（称为grits）。美国人煮后加入奶油和糖食用，在大连则不加其它佐料，称为葛子粥。

Grits is a food made by boiling ground maize (also known as corn) and usually served with other flavorings as a breakfast dish, usually savory. It is popular in the Southern United States.

Grits is of Native American origin and is similar to other thick maize-based porridges from around the world such as polenta.
