Patricia Calton (née Yeldon; 19 September 1948 – 29 May 2005) was a British Liberal Democrat politician who served as Member of Parliament (MP) for Cheadle in Greater Manchester.

She held her seat in the 2005 general election with a majority of 4,020 votes over Stephen Day, despite being too ill with cancer to campaign personally.

Calton was born into a Royal Air Force family and as a result moved around frequently as a child.

Either side of a career break while bringing up her family, she taught Chemistry in comprehensive schools in Greater Manchester and Cheshire.

In Parliament, she was a Liberal Democrat spokeswoman on Northern Ireland and on health, and was also chair of the all-party group on breast cancer.
