A public house, usually known as a pub, is an establishment which serves alcoholic drinks for consumption on the premises, usually in a homely setting. Pubs are commonly found in English-speaking countries, particularly in the United Kingdom, Ireland, Canada, Australia and New Zealand.

In North America, drinking establishments with a British or Irish name or theme are called pubs as well; the appellation "pub" itself is often a component of this theme. Although the terms may have different connotations, there is no definitive difference between pubs, bars, taverns and lounges where alcohol is served commercially.
