Malvina Cavallazzi (born about 1852 – died October 23, 1924) was an Italian ballet dancer active in New York City and London.

Cavallazzi was born in Ravenna, and trained as a dancer at La Scala in Milan.

Cavallazzi has never danced more beautifully and gracefully, and gave positive pleasure," the New York Times reported of her performance at a benefit program in 1882, adding that "it would, in fact, but difficult to imagine any danseuse who could have been more perfect in her work.

[1] Critic Arthur Symons found that she was "not by any means without talent," but that "she so deliberately and resolutely overdoes everything she has to do as to absolutely tire one's eyes.

Her students included Eva Swain,[8] Phyllis Bedells,[9] Marjorie Bentley,[10] and Winifred Hart-Dyke.
