Maria Spezia-Aldighieri (1828–1907) was an Italian operatic soprano who had an active international career from 1849 up into the 1870s. She excelled in the coloratura soprano repertoire and was particularly admired for her portrayals in the operas of Giuseppe Verdi. Her performance of Violetta in Verdi's La traviata at the Teatro San Benedetto in Venice in 1854 is credited with popularizing the opera after it had initially flopped at its premiere in 1853. She was married to baritone Gottardo Aldighieri and is the great grandmother of singer George Aaron.
