Randal Hume Keynes, OBE, FLS (/ˈkeɪnz/ KAYNZ; 29 July 1948 – 3 March 2023) was a British conservationist, author, and great-great-grandson of Charles Darwin.

Randal Keynes has two children with Zelfa Cecil Hourani, also from a prominent intellectual family, originally from Lebanon.

Randal and Zelfa's son, Skandar Keynes (born 1991), is a political advisor and former actor best known for his role as Edmund Pevensie in the Narnia films.

[3] He campaigned successfully against the redevelopment of King's Cross station and for the preservation of the Caledonian Road neighbourhood in central London.

He recalls one of the turning points as his persuasion of two members of the House of Lords to ask the government to guarantee the funding of the project; when the ministers declined to, the bill fell.
