Chloe Rebecca Smith (born 17 May 1982) is a British Conservative Party politician who served as the Member of Parliament (MP) for Norwich North from 2009 to 2024. She previously served as Secretary of State for Work and Pensions from September to October 2022 and Secretary of State for Science, Innovation and Technology from April to July 2023.

Smith was elected in a 2009 by-election following the resignation of Labour MP Ian Gibson due to the MPs' expenses scandal. Smith held a number of junior ministerial roles under David Cameron and Theresa May, serving two terms as Parliamentary Secretary for the Constitution. She continued to serve in the latter role after Boris Johnson's victory in the 2019 Conservative Party leadership election.

In the February 2020 reshuffle, Smith was promoted to Minister of State during the second Johnson ministry. In the 2021 reshuffle, she was appointed by Johnson as Minister of State at the Department for Work and Pensions. After Johnson resigned in 2022, Smith supported Liz Truss’s bid to become Conservative leader. Following Truss's appointment as Prime Minister, she appointed Smith as Secretary of State for Work and Pensions. She was later temporarily Secretary of State for Science, Innovation and Technology during the time Michelle Donelan MP was Minister on Leave (Secretary of State), a position given to Secretaries of State and Ministers of State while on maternity leave.

Chloe Smith was born in Ashford, Kent, in 1982. Her family moved to Stoke Ferry, Norfolk, when she was three years old, and she attended comprehensive schools in Swaffham and Methwold. After a gap year working for former Conservative Education Secretary Gillian Shephard, she read English Literature at the University of York. She undertook summer work for Bernard Jenkin.

After graduating from the University of York, Smith joined Deloitte Touche Tohmatsu as a management consultant. She advised private businesses, government departments and public bodies.

In 2007, Smith was chosen to be the Conservative Party candidate for the constituency of Norwich North at the general election. She then took leave from her job, working for Conservative Central Office on secondment, to "draw up detailed plans to put our policies into practice".

Following the resignation of Labour MP Ian Gibson as a result of the MPs' expenses scandal, Smith became the Conservatives' by-election candidate. At the 2009 Norwich North by-election, Smith was elected, winning with 39.5% of the vote and a majority of 7,348. Smith became the youngest member of the House of Commons. She took her seat in the House of Commons when the parliamentary break ended in October.

At the 2010 general election, Smith was re-elected as MP for Norwich North with an increased vote share of 40.6% and a decreased majority of 3,901.
