Cosimo de' Medici was an Italian banker and politician, the first of the Medici political dynasty, de facto rulers of Florence during much of the Italian Renaissance. Despite his influence, his power was not absolute; Florence's legislative councils at times resisted his proposals, something which would not have been tolerated by the Visconti of Milan, for instance; throughout his life he was always primus inter pares, or first among equals. His power derived from his great wealth as a banker, and he was a great patron of learning, the arts and architecture.

Cosimo dei Migliorati was the birthname of Pope Innocent VII (Pontificate between 1404-1406).

Cosimo is the child of singer Beck Hansen (more commonly known as "Beck") and actress Marissa Ribisi.
