Heather Nicholson (born 30 January 1967), also known as Heather James, is a British animal rights activist. She is best known for having co-founded three pivotal animal rights campaigns in the UK in the 1990s. In 1997, Consort Kennels in Hereford, which bred beagles for animal-testing labs, was closed after a ten-month campaign led by Nicholson and her husband at the time, Greg Avery.
