Marjorie L. Pieper ["Peeps"] (August 2, 1922 – February 6, 2008) was an infielder, outfielder and pitcher who played from 1946 through 1952 in the All-American Girls Professional Baseball League.

[4] Pieper entered the league in 1946 with the Fort Wayne Daisies, playing one and a half years for them before joining the Kenosha Comets (1947–1948) and the Chicago Colleens (1948).

She played exclusively at shortstop in Fort Wayne and Kenosha, hitting a .173 batting average in her rookie season.

She also tied for fourth in doubles (11) and belted five home runs, being surpassed only by Kenosha's teammate Audrey Wagner (7) and Rockford Peaches' Dorothy Kamenshek (6).

She came back to Kenosha in 1950, for a short time, because she was assigned to the Peoria Redwings (1950–1951) before joining the Battle Creek Belles (1951–1952).
