Rozalind Elsi Franklin (engl. Rosalind Elsie Franklin; 25. jul 1920 — 16. april 1958)[1] je bila britanska biofizičarka i kristalografkinja. Njen rad sadrži ključni doprinos razumevanju fine molekulske strukture DNK, RNK, virusa, uglja i grafita.[2] Najpoznatija je po radu na DNK jer dezoksiribonukleinska kiselina ima esencijalne uloge u ćelijskom metabolizmu i genetici. Otkriće njene strukture je pomoglo naučnicima da razumeju način na koji se genetička informacija prenosi sa roditelja na decu.
Franklin je najpoznatija po njenom difrakcionom snimku DNK koje je dovelo do otkrića DNK dvostrukog heliksa. Njeni podaci su prema izjavi Fransisa Krika korišćeni[3] 1953. za formulisanje hipoteze o strukturi DNK.[4] Franklinovi snimci difrakcije X-zraka koji su potvrdili heliksnu strukturu DNK su pokazani Votsonu bez njenog odobrenja ili znanja. Mada su taj snimak i njena precizna interpretacija pružili značajan uvid u DNK strukturu, njen naučni doprinos tom otkriću se retko navodi. Njen neobjavljeni manuskript pokazuje da je ona nezavisno utvrdila sveukupnu B-formu DNK heliksa i lokaciju fosfatnih grupa na obodu strukture.[5]
Nakon rada na DNK, Franklin je izučavala viruse mozaika duvana i polio. Ona je preminula 1958 usled komplikacija izazvanih rakom jajnika.
