Eligio Sardiñas Montalvo (January 6, 1910 – August 8, 1988), better known as Kid Chocolate, was a Cuban boxer who enjoyed great success both in the boxing ring and outside it during the 1930s.

He later sparred with boxers such as Benny Leonard and Jack Johnson, all world champions, before beginning an amateur boxing career.

He started 1932 by winning his first eight bouts, including a world title defense in Havana against Davie Abad, beaten in 15 by decision.

He engaged in seven more bouts, including two decision wins over Johnny Farr, before fighting Lew Feldman on October 13.

He defended that world title twice, including a third fight with LaBarba, before relinquishing it while in the middle of a European boxing tour that took him to Madrid, Barcelona and Paris.

Before a crowd of 4,000, the Kid lost the World Jr. Lightweight boxing championship to Frankie Klick, on December 25, 1933, at the Arena in Philadelphia, Pennsylvania, in a seventh-round technical knockout.

The Ludington Daily News, wrote "The flashy Cuban "bon bon" (Chocolate) was bereft of the title in the seventh round of a scheduled fifteen round Christmas Day bout by a whistling right smash to the chin and all he got in exchange was the second knockout of his career although the latest was of the technical variety."

He mixed the concentration, masterful combinations and power punching of Louis with the stylish movement and balance of Chocolate.
