|Locust Alley (until 1881)|
|Spruce Alley (until 1881)|
|Eden Alley (1881–1914)|
The part between 43rd Street and 47th Street was originally named Spruce Alley.
Bob Regan includes "Eden" in his "Streets of Pittsburgh" crossword puzzle, clued as "The beautiful garden where Adam and Eve were placed at the Creation." Unfortunately this is just a dictionary definition of the name Eden and gives no information about the origin of the alley name.
