Saving Planet Earth is a season of nature documentaries with a conservation theme, screened on BBC Television in 2007 to mark the 50th anniversary of its specialist factual department, the BBC Natural History Unit.

The series featured films contributed by a number of celebrities on the plight of various endangered species, and coincided with the launch of the BBC Wildlife Fund, a charitable organisation which distributes money to conservation projects around the world. The television series culminated in a live fundraising telethon on BBC Two, hosted by Alan Titchmarsh, which raised over £1 million for the charity.

The BBC broadcast a second live telethon in 2010. Wild Night In was presented by Kate Humble, Chris Packham and Martin Hughes-Games and featured conservation projects which had benefited from the support of the BBC Wildlife Fund. This helped to raise a further £1 million.
