The first King of Spain was Carlos I of Spain. He was also Charles V, Holy Roman Emperor.

Before Carlos I the Iberian Peninsula was occupied by smaller kingdoms and principalities each with it's own ruler/monarch. Spain was never truly unified until Carlos inherited the Kingdoms of Castile, Leon, and Aragon bringing Spain into existence as a single Monarchy.
The first king of the combined Kingdom of Spain was Charles I. Charles was the first king after the Kingdom of Aragon and Kingdom of Castile combined to form Spain.
