Edward (Eduard) Issakovich Gerstenfeld (January 1915 in Lviv – December 1943 (?) in Rostov-on-Don, USSR) was a Polish chess master.
Born into a Jewish family in Lviv, Galicia (then Austria-Hungary), he came 3rd, behind Henryk Friedman and Izaak Schächter, in the Lviv City championships in 1933. He came 3rd at Lviv 1933 (LKSz, Oskar Piotrowski won), 7th in the Lviv City-ch, and came first in the Lviv City-ch in 1935.
In the period between 1935 and 1939, he lived in Łódź. In 1935, Gerstenfeld shared 4th with Jakub Kolski, behind Izaak Appel and Achilles Frydman, in Łódź (quadrangular). He tied for 2nd-5th with A. Frydman, Schächter and Abram Szpiro in Łódź (pre-Olympic tournament, Friedman won), and took 15th in Warsaw (the 3rd Polish Chess Championship, Savielly Tartakower won). In 1936, he played a match against Szpiro in Łódź, shared 2nd with Schächter, behind Szpiro, at Częstochowa (POL-ch elim.), and tied for 2nd with Appel, behind A. Frydman, in Łódź (ŁTZGSz).
