Edward Leroy Koffenberger (July 4, 1926 – September 21, 2014) was an American stand-out basketball and lacrosse player for the Duke University in 1945–46 and 1946–47.

He is considered Duke's first "two-sport star"[1] even though most of his accolades came from playing basketball.

A native of Wilmington, Delaware, Koffenberger was the only First Team All-American basketball player from his home state when the Helms Foundation awarded him the distinction.

[1] In 54 career basketball games he scored 733 points, including a then-Duke record 416 in 1946–47.

[2][3] Koffenberger was selected by the Philadelphia Warriors in a late round of the 1947 BAA draft, although he only briefly played professionally but never in the Basketball Association of America.
