The North Atlantic League was the name of two minor baseball leagues. The first was a Class D affiliated system that operated from 1946 until 1950, and the second was an independent minor league that played from 1995 until 1996. Three of that league's franchises joined the Northeast League after the folding of the North Atlantic League.

Many ballplayers with major league experience played in the league, including Tom Marsh, Carl Sawatski, Bill Burich and Lonnie Goldstein, among others.
