Pi Kappa Delta (ΠΚΔ) is an American honor society and organization for intercollegiate debaters, public speakers, and instructors teaching speech, debate, and oral communication.

Phi Kappa Delta was stablished in 1913 at Ottawa University as an honor society and organization for intercollegiate debaters, public speakers, and instructors teaching speech, debate, and oral communication.

However, when used for academic cords or stoles, Cardinal red and slate grey are substituted.

PKD publishes a refereed journal entitled The Forensic of Pi Kappa Delta.

A cross-section of articles would include topics ranging from debate to individual events to philosophical issues related to competition and forensic education.

PKD sponsors programs at the annual National Communication Association convention.
