A new method to extract the weak phase gamma is suggested by exploiting B --> DK(*) decay modes that are not Cabibbo suppressed, using the isospin relations, and ignoring the annihilation diagram as usual. Assuming a 3 x 10(8) B (B) over bar pair at B factories, one can determine gamma with a 3 sigma accuracy for 80 degrees less than or similar to gamma less than or similar to 150 degrees using B --> DK modes and for 50 degrees less than or similar to gamma less than or similar to 170 degrees using B --> DK* modes.
