Santorre Annibale De Rossi di Pomerolo, Count of Santa Rosa (born 18 November 1783, Savigliano – died 8 May 1825, Sphacteria) was an Italian insurgent and leader in Italy's revival (Risorgimento).

The revolutionary and imperial epoch stimulated Italian patriotism, and Santarosa was aggrieved by the extension given to the Austrian power in Italy in 1815, which reduced his country to a position of inferiority.

The conspirators endeavoured to obtain the cooperation of the prince of Carignano, afterwards King Charles Albert, who shared their patriotic aspirations.

He fled to France, and lived for a time in Paris under the name of Conti, where he wrote in French and published, in 1822, La Revolution Piemontaise, which attracted the notice of Victor Cousin.

After a short stay first at Alençon and then in Bourges, he travelled to England, where he found refuge in London with the poet Ugo Foscolo, and made English friends.
