Sarah Deborah Champion (born 10 July 1969) is a British Labour Party politician who has served as the Member of Parliament (MP) for Rotherham since 2012.

Champion is Chair of the International Development Select Committee, a position she was first elected to in 2020. She was re-elected to the role shortly after the 2024 general election.

Champion was appointed by Jeremy Corbyn as Shadow Minister for Preventing Abuse in September 2015. She resigned in June 2016, but returned to the frontbench shortly after, in the same post.

In October 2016, she was promoted to the Shadow Cabinet as Shadow Secretary of State for Women and Equalities, which she stepped down from in August 2017, following her article on grooming gangs.

Champion studied psychology at Sheffield University. Before entering Parliament, she ran a Chinese Arts Centre in Manchester and was employed as the Chief Executive of a children's hospice in Rotherham.

Champion was first elected to Parliament at Rotherham's 2012 by-election.

In November 2012 Champion was selected to be Labour's candidate for the upcoming Rotherham by-election, which was triggered by the resignation of the constituency's MP, Denis MacShane. At the by-election, Champion was elected as MP for Rotherham with 46.3% of the vote and a majority of 5,318.

In an interview with BBC Radio Sheffield on 30 November 2012, Champion said that she does not regard herself as being a career politician: "There are some people who from the moment they were born wanted to be a politician. Whereas for me, since I started working I've always been working with the community and I want to carry on doing that."
