米饭又称白饭，简称饭，是一种用稻米与水煮成的食物。米饭是中国、日本和朝鲜等东亚地区最主要的粮食。米饭制法为一杯米加一杯到一杯半的水（米水体积比为1:1或1:1.5，越多的水将使米饭的口感越软烂），煮出来的米适当的膨胀，里面全熟，去除水份后即成。在香港的酒楼和茶餐厅，白饭亦有俗称为靓仔，惟来源已不可考。

米饭的面世，可追溯至粥。由于烹煮粥水控制水量的要求比米饭低，上古的华夏民众后来慢慢掌握不同水量时的烹煮效果，就发展出较饱满的米饭。现代由于打磨谷粒的技术比古代越趋先进，因此民众食用的米饭也渐渐由糙米改用白米，甚至出现免淘洗米等净白米，但已失去存于糙米表面即谷糠的各种营养，而几乎只剩下淀粉质等糖份，因此也同时引发现代民众患糖尿病个案上升的其中原因之一(非主要原因)。

Steamed rice refers to rice that has been cooked either by steaming or boiling. Steamed rice includes any variant, including short, medium, and long grain rice.

Rice is a staple food in not only Asia and Latin America, but across the globe, and is considered the most consumed food in the world. The U.S. Department of Agriculture classifies rice as part of the grains food group -- each cup of cooked steamed white rice contributes 2 ounces toward the daily recommended 6 and 7 ounces for women and men, respectively, and is considered a good source of micronutrients such as zinc and manganese.
