Nicholas Dominic Dallessandro (October 3, 1913 – April 29, 1988) was an outfielder in Major League Baseball who played for two teams between 1937 and 1947.

Dallessandro entered the majors in 1937 with the Boston Red Sox, playing for them one year before joining the Chicago Cubs in 1940.

He enjoyed another solid season in 1944, hitting a career-high .304 with eight home runs and 74 RBI in 117 games.

He missed 1945 due to military service during World War II and rejoined the Cubs in 1946, playing for them in part of the next two seasons.

Known by the alliterative but uncomplimentary nickname "Dim Dom" and also as "Mr. 5-by-5", short of stature, he was referenced in Chicago columnist Mike Royko's annual Cubs quiz on April 18, 1968: Dallessandro's nephew Dick Gernert also played in the major leagues.
