Pedro V of Portugal (September 16 1837 - November 11 1861) was King of Portugal from 1853 to 1861.

He was the oldest son of Queen Maria da Glória and her King-Consort Ferdinand II. Pedro was an unusually conscientious and hard-working monarch who, under the guidance of his father, sought radical modernisation of the Portuguese state and infrastructure. Under Pedro's reign roads, telegraphs and railways were constructed and improvements in public health advanced.

However, this was unable to save the life of the young king who died (along with his brother Ferdinand) of cholera in 1861. He was married to Stephanie, Princess of Hohenzollern Sigmaringen, but had no successors and the throne then passed to brother Luis.
