Bernard Rollen Williams III (born January 19, 1978) is an American male former track and field sprinter and winner of a gold medal in 4 × 100-meter relay at the 2000 Summer Olympics.

Acquiring the nickname "Hollywood", he was personally noted for his comedy antics during the 2000 Olympics, including using "the people's eyebrow" – a pose used by then-professional wrestler Dwayne "The Rock" Johnson.

Also, known for his pre race antics and poses playing to any crowd, which grew to be increasingly accepted in the sport following the celebrations of multiple Olympic champion Usain Bolt.

He tested positive for cannabis and received a warning from the USADA in August 2004, but was still able to compete in the Olympics in accordance with IAAF rules.

The Americans performed to a booing audience, as the Greeks protested the exclusion of the 2000 Olympic champion Kostas Kenteris for doping.
