Sir David Frederick Attenborough (/ ˈ æ t ən b ə r ə /; born 8 May 1926) is a British broadcaster, biologist, natural historian, and writer. He is best known for writing and presenting, in conjunction with the BBC Studios Natural History Unit, the nine nature documentary series forming the Life collection, a comprehensive survey of animal and plant life on Earth.

Attenborough was a senior manager at the BBC, having served as controller of BBC Two and director of programming for BBC Television in the 1960s and 1970s. First becoming prominent as host of Zoo Quest in 1954, his filmography as writer, presenter and narrator has spanned eight decades; it includes Natural World, Wildlife on One, the Planet Earth franchise, The Blue Planet and its sequel. He is the only person to have won BAFTA Awards in black and white, colour, high-definition, 3D and 4K resolution. Over his life he has collected dozens of honorary degrees and awards, including three Emmy Awards for Outstanding Narration.

While Attenborough's earlier work focused primarily on the wonders of the natural world, his later work has been more vocal in support of environmental causes. He has advocated for restoring planetary biodiversity, limiting population growth, switching to renewable energy, mitigating climate change, reducing meat consumption, and setting aside more areas for natural preservation. On his broadcasting and passion for nature, NPR stated Attenborough "roamed the globe and shared his discoveries and enthusiasms with his patented semi-whisper way of narrating". He is widely considered a national treasure in the UK, although he himself does not embrace the term.
