The Welsh (Welsh: Cymry) are a nation and ethnic group native to, or otherwise associated with, Wales, Welsh culture, Welsh history, and the Welsh language. The language, which falls within the Insular Celtic family, has historically been spoken throughout Wales, with its predecessor Common Brittonic once spoken throughout most of the island of Great Britain. Prior to the 20th century, large numbers of Welsh people spoke only Welsh, with little or no fluent knowledge of English. Welsh remains the predominant language in parts of Wales, particularly in North Wales and West Wales, but English is the predominant language in most parts of the country. Many Welsh people, even in predominately English-speaking areas of Wales, are fluent or semi-fluent in Welsh or, to varying degrees, capable of speaking or understanding Welsh at limited or conversational proficiency levels.

Although the Welsh language and its ancestors have been spoken in what is now Wales since well before the Roman incursions into Britain, historian John Davies argues that the origin of the "Welsh nation" can be traced to the late 4th and early 5th centuries, following the Roman departure. The term "Welsh people" applies to people from Wales and people of Welsh ancestry perceiving themselves or being perceived as sharing a cultural heritage and shared ancestral origins. Wales is a country that is part of the United Kingdom, and the majority of people living in Wales are British citizens.
