Almond milk is a plant-based milk substitute with a watery texture and nutty flavor manufactured from almonds, although some types or brands are flavored in imitation of cow's milk. It does not contain cholesterol or lactose and is low in saturated fat. Almond milk is often consumed by those who are lactose-intolerant and others, such as vegans, who do not consume dairy products.

Commercial almond milk comes in sweetened, unsweetened, vanilla and chocolate flavors, and is usually fortified with micronutrients as a processed food.

Almond milk can also be made at home using a blender, almonds and water.

Global almond milk sales in 2018 were US$5.8 billion, growing at 14% per year, and forecast to be a $13 billion global market by 2025.
