Isabella Angela Colbran (2 February 1785 – 7 October 1845) was a Spanish opera singer known in her native country as Isabel Colbrandt.
Many sources note her as a dramatic coloratura soprano but some believe that she was a mezzo-soprano with a high extension, a soprano sfogato.
She collaborated with opera composer Gioachino Rossini in the creation of a number of roles that remain in the repertory to this day; they were married on 22 March 1822.
She was the composer of four collections of songs.
