Reginald Keil Dupree (born 10 December 1987) is an American-Icelandic basketball player for Keflavík of the Úrvalsdeild karla.

[1] Dupree started his career with Reynir Sandgerði in the 1. deild karla.

As the rules at the time only allowed one non-EU player on the court, he played sparingly, averaging 4.4 points in 10.1 minutes per game.

The following summer, Dupree received an Icelandic citizenship and as a result his playing time and performance increased[3] with his averages jumping to 11.4 points in 29.5 minutes per game while shooting a career high 48.9% from the three point line.

[2] In October 2016, Dupree was ejected from a game against Stjarnan after a minor confrontation with Justin Shouse ended with Dupree throwing Shouse's headband up to the stands.
