Sylvia Lopez (November 10, 1933 – November 20, 1959) was a French model and actress. Born Tatjana Bernt, she was raised in Paris, where she began a career in modelling.

Eventually she modeled for couturier Jacques Fath, the first French fashion designer to export his creations to the United States. Appearing under the name "Sylvia Sinclair", Bernt earned enough exposure to attract the attention of film producers. In November 1956 she became the second wife of the composer Francis Lopez.
