Diosdado Posadas (December 25, 1906 - July 2, 1990), better known as Speedy Dado, was a Filipino boxer.
Dado began his boxing career in 1926. He was undefeated until he met Newsboy Brown in 1928 for the California version of the world flyweight title. Brown defeated him by knockout in the sixth round. He met Brown again twice more, winning one fight and losing the other.
Dado fought for world titles on three other occasions, losing all of them. He lost a 1933 fight to Baby Arizmendi for the California version of the world featherweight title, another fight in 1933 to Freddie Miller for the National Boxing Association featherweight title, and a 1935 fight against Pablo Dano for the California version of the bantamweight world title.
