Landi Swanepoel (born 8 October 1979 in Cape Town) is a South African model.
She is known for her campaigns for Guess?, but her highest accolade was her selection as the "Sylvia" character in Peroni's Nastro Azzurro beer commercial that pays homage to Federico Fellini's La Dolce Vita. The role was originally played by Anita Ekberg. She was discovered as a model when she was fourteen while shopping with her mother.
