Dale Leonard Alderson (March 9, 1918 – February 12, 1982) was a pitcher in Major League Baseball who played from 1943 through 1944 for the Chicago Cubs.

A native of Belden, Nebraska and graduate of Upper Iowa University, Alderson was one of many major leaguers who saw his baseball career interrupted by a military stint during World War II.

During the 1944 midseason, he was optioned back to Nashville, where he enlisted the Navy though he had twice been previously rejected because of a kidney ailment.

In a two-season career, Alderson posted a 0–1 record with a 6.56 ERA in 16 appearances, including three starts, giving up 30 runs (four unearned) on 52 hits and 12 walks while striking out 11 in 352⁄3 innings of work.

Alderson served as a seaman first class in the United States Navy during World War II.
