Peoples Trust for Endangered Species (PTES) is a charitable organisation registered in England and Wales. It exists to promote the conservation of rare or declining species and habitats in the UK and worldwide through monitoring, public engagement, education, and through the funding of conservation projects and research. It also owns and manages two nature reserves. As of April 2015, PTES has 16 employees, five trustees and coordinates around 24,000 volunteers in the UK. PTES relies on donations from the general public and grants from trusts and foundations to continue its work - it receives no core funding from the UK Government. The organisation has registered charity number 274206.

PTES was founded in 1977. Originally based in South Kensington at Imperial College London, in 1993 the organisation moved to its present location in Battersea, south-west London. In 2001 PTES developed Mammals Trust UK, a restricted fund and campaign targeting the conservation of British mammals. In 2006, Mammals Trust UK was incorporated under the activities of PTES. PTES still operates a ring-fenced funding stream for British mammals but the names ‘Mammals Trust UK’ and 'Mammals Trust' have since been disbanded.
