The Imperial Order of Dom Pedro I is a Brazilian order of chivalry instituted by Emperor Pedro I of Brazil on 16 April 1826. It is considered by many numismatists as the rarest of the Brazilian imperial orders.

Dom Pedro I was the founder and first ruler of the Empire of Brazil, where he was known as "the Liberator". As King Dom Pedro IV, he reigned briefly over Portugal, where he also became known as "the Liberator" as well as "the Soldier King". Born in Lisbon, Pedro I was the fourth child of King Dom John VI of Portugal and Queen Carlota Joaquina, and thus a member of the House of Braganza. When the country was invaded by French troops in 1807, he and his family fled to Portugal's largest and wealthiest colony, Brazil.
