Charles "Lil Buck" Riley (born May 25, 1988) is an American dancer, actor and model from Memphis, Tennessee, who specializes in a style of street dance called jookin.

He gained popularity after director Spike Jonze used his cell phone to record an interpretive performance of The Dying Swan by Lil Buck and Yo-Yo Ma.

In 2011, director and former ballet dancer Damian Woetzel met Lil Buck and paired him with Yo-Yo Ma in "The Swan" performance that went viral on YouTube.

Woetzel heard about Lil Buck from his wife Heather Watts who saw an old YouTube video clip of Lil Buck freestyle dancing to Camille Saint-Saëns’ Le cygne (The Swan) in a New Ballet Ensemble (NBE) school performance in West Memphis, Arkansas.

They all eventually met by using Facebook to contact Katie Smythe (Lil Buck's ballet teacher) who facilitated the introduction.

After his trip, Lil Buck was photographed by Bruce Weber for an interview in the Spring 2011 issue of VMan magazine.

[27] Lil Buck performed with Yo-Yo Ma a third time at an event directed by Woetzel and held at (Le) Poisson Rouge in New York City.

[28] Later in the year, Lil Buck made the August 2013 cover of Dance magazine[29] and briefly appeared in the Spike Jonze film Her as a busker/dancer.
