Rona Ambrose, PC, MP, MA (born March 15, 1969 in Valleyview, Alberta) is Canada's Minister of the Environment. She has been a Conservative member of the Canadian House of Commons from Edmonton—Spruce Grove since 2004. She is a former communication consultant and public policy consultant for the Alberta government. When her party was in opposition, she was the Conservative Party's Intergovermental Affairs critic.

Ambrose has a Bachelor of Arts from the University of Victoria and a Master of Arts degree in political science from the University of Alberta.

Ambrose grew up both in Brazil and in Parkland County, Alberta. In addition to English, she also speaks fluent Spanish, Portuguese, and intermediate French.

On February 16, 2005, she made headlines after making a stinging remark in Parliament directed at Liberal Social Development Minister Ken Dryden saying "working women want to make their own choices, we don't need old white guys telling us what to do," in reference to the Liberal national child care plan.

Ambrose is considered a strong representative of contemporary Canadian Conservatism under current leader Stephen Harper: young, female, and not uncomfortable with Big Government bureaucracy, a topic often railed against by her party's predecessors in the Reform Party and Canadian Alliance. Among her own party, she is being cited as a potential leadership contender.

Ambrose was temporarily the Conservative critic for International Trade after the defection of Belinda Stronach to the Liberal Party.

In 2006, Rona Ambrose successfully defended her seat in Edmonton--Spruce Grove with 66.6% of the vote in the riding. She was then appointed Environment Minister in Prime Minister Stephen Harper's government.
