The London scheme, from English Heritage, will also celebrate novelist Barbara Pym, artist Graham Sutherland, ballerina Alicia Markova and Jamaican writer and campaigner Una Marson.
T Rex frontman Bolan will be marked with a plaque at one of his west London addresses, while English National Ballet co-founder Markova is set to be honoured at her childhood home in Muswell Hill.
English Heritage curatorial director, Matt Thompson, said: “2025 marks an exciting year for the Blue Plaques Scheme as we honour these outstanding individuals who transformed the cultural fabric of London.
More London locations will be picked for Marson, claimed by the BBC to be its first black producer on the payroll who would go on to develop Caribbean Voices, part of the Calling The West Indies series, as well as Excellent Women author Pym.
Hepburn also has four Academy Award best actress nods for romantic comedies Sabrina and Breakfast At Tiffany’s, drama The Nun’s Story, and horror Wait Until Dark.
