Francisco Marihno Robby Elson (born February 28 1976 in Rotterdam, Netherlands) is a professional basketball player in the NBA of African-Dutch nationality. He was drafted in the second round of the 1999 NBA Draft from Cal by the Denver Nuggets, but didn't commence play with them until the 2003-04 campaign. Over two seasons, he has career averages of 3.6 points and 3.1 rebounds per game.

Elson caused controversy in April, 2004, when after a playoff game against the Minnesota Timberwolves in which he was accidently hit in the groin by opposing player Kevin Garnett, described Garnett as "gay". He was quoted as saying: "That's a cheap shot by a low-class type player. You don't do that. That's gay on his part. I told him that he was gay, too, for touching me in my private parts."

He later apologized for his comments.
