The 1947–48 BAA season was the second season of the Basketball Association of America. (Following its third, 1948–49 season, the BAA and National Basketball League merged to create the National Basketball Association or NBA.) The postseason tournament (the 1948 BAA Playoffs), at its conclusion ended with the Baltimore Bullets winning the BAA Championship, beating the Philadelphia Warriors 4 games to 2 in the BAA Finals.
Although not celebrated at the time, this season was historic, with Wataru Misaka of the New York Knicks becoming the first person of color to play in modern professional basketball.
The NBA recognizes the three BAA seasons as part of its own history, sometimes without comment, so the 1947–48 BAA season is sometimes considered the second NBA season.
