No, Poland is not part of the United Kingdom. They are separate sovereign states with distinct histories, governments, and geographies.

Poland

• EU/NATO member.

United Kingdom

Historical Note

Poland and the UK were WWII allies (Polish forces fought under British command). Post-war, Poland fell under Soviet influence; the UK helped establish NATO. Since 1989, both are democratic allies in NATO and (until Brexit) the EU. Large Polish diaspora in the UK (~700,000).

Confusion sometimes arises from migration ties or WWII history, but politically and legally, they are entirely independent.
