Osborne Earl "Nikko" Smith Jr. (born April 28, 1982) is a singer-songwriter who was the ninth-place finalist of the fourth season on American Idol.

On October 26, 2006, Smith performed "The Star-Spangled Banner" prior to Game 4 of the World Series, at the home field of the St. Louis Cardinals for whom his father had played 15 seasons.

Smith made it to the third round of the semi-finals, but was voted off on March 9 along with Travis Tucker.

Days later, Smith got a phone call from the producers asking him to come back in place of Mario Vazquez, who left for "family reasons".

After returning, Nikko was dubbed "The Comeback Kid" by judge Paula Abdul after a performance of "One Hand, One Heart".
