Louis Bartlett Costello (September 14, 1876 – May 6, 1959) was an American newspaper publisher and banker who served as general manager and then president of The Lewiston Daily Sun and Lewiston Evening Journal in Lewiston, Maine. He began his career in journalism while still a student at Bates College and, by the end of his life, was a leading press figure in the state.

For nearly a half century, Costello was one of the most prominent members of the Lewiston-Auburn community. In addition to running its largest morning and afternoon papers, he was a longtime trustee of both Bates College and the Androscoggin County Savings Bank, serving as the latter institution's president from 1931 to 1939. He was an active Freemason and member of the United Baptist church.
