食堂，也叫饭堂，常见于学校、公司、工厂和军营，是大量人群集体用餐的地方。

食堂的内部设施主要是桌、椅、收款处和厨房摊位。现在一般的食堂也提供风扇或者空调。

食堂通常类似快餐店经营，一般是先付款，后取收据到厨房窗口去取食物。有些食堂出菜部一般分为几个，分别售卖不同种类的食物，增加去食堂进餐的人的选择范围。出菜部一般分为水吧、烧味部、中餐、西餐等。

A cafeteria is a type of food service location in which there is little or no waiting staff table service, whether a restaurant or within an institution such as a large office building or school; a school dining location is also referred to as a dining hall or canteen (in British English). Cafeterias are different from coffeehouses, despite being the Spanish translation of the English term.
