Orrington was originally part of Condustiegg (or Kenduskeag) Plantation, which also included the present-day cities of Bangor and Brewer. Orrington was incorporated as a town in 1788 with its major village at Brewer, then called "New Worcester". Bangor incorporated three years later in 1791. Brewer broke away from Orrington in 1812 to form a separate town.
The name "Orrington" reportedly resulted from a spelling mistake. The settlers intended to name it "Orangetown" after Orangetown, Maryland, but it was written on the record-books in distant Massachusetts, of which Maine was then a territory, as "Orrington". "Orring" was not an unreasonable phonetic rendering of "orange" before the standardization of spelling.
