A blender is a kitchen appliance used to blend ingredients or puree food. The term typically refers to a stationary, upright electrical device, which is to be distinguished from a hand-powered or electric mixer that may be used for similar purposes.

A typical blender will be built around a vessel for the ingredients to be blended. At the top of the vessel will be a cap to prevent ingredients from escaping when the blender is switched on. At the bottom will be a blade assembly, typically removable for cleaning purposes. The bottom seal will most likely be watertight. The vessel will rest upon a base containing a motor (for turning the blade assembly) with controls on its surface. Most modern blenders will offer a number of possible speeds.
