Orien Randolph Greene II (born February 4, 1982) is an American former professional basketball player.

However, in 2007, an NCAA investigation found that Greene had relied on 15 hours of correspondence courses taken through another institution in order to remain eligible for the 2004 spring semester and the entire 2004–05 academic year.

According to the NCAA, this was an "obvious error" that should have been caught right away, but the school's then-compliance coordinator director of academic services and registrar all failed to catch it.

His status as the backup point guard was cemented by a season-ending injury to Dan Dickau and the trade of Marcus Banks to the Minnesota Timberwolves.

The Pacers brought in Darrell Armstrong (from Dallas) and Keith McLeod (from Golden State) to compete with Greene for minutes at point guard.

With Jamaal Tinsley holding the starting position, Greene fell to fourth on the depth chart, which resulted in very little playing time.
