This article is about the physical container. For uses in the field of computing see Bucket (computing).

A bucket, also called a pail, is a waterproof, vertical cylinder, open at the top and with a solid bottom, usually attached to a carrying handle and usually wider at the top. Buckets have been used since very ancient times, mainly for transporting water from a fountain or well into permanent reservoirs such as water holes and barrels.

At one time it was common for workers to carry food in a bucket and it was called a "lunch bucket" or "lunch pail". Following this practice, manufacturers began to construct buckets and other containers specifically for carrying food. See: lunchbox.

Bucket is also a mobile compartment for minerals and materials - mainly sand, dirt, minerals, and liquids (water). It enables storing, as well as rapid filling and emptying.

Bucket is also used to denote the scoop installed on a front loader, backhoe, or other industrial equipment .
