The Baltimore oriole is a small icterid (New World) blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of 17th century Lord Baltimore.

Baltimore orioles are found in the Nearctic in summer, including the Canadian Prairies and eastern Montana in the northwest eastward through southern Ontario, southern Quebec, and New Brunswick and south through the eastern United States to central Mississippi and Alabama and northern Georgia. They migrate to winter in the Neotropics as far north as Mexico and sometimes the southern coast of the United States, but predominantly in Central America and northern South America.

The Baltimore oriole is the state bird of Maryland. It is also the namesake and mascot for the Baltimore Orioles baseball team.
