Tonique Williams-Darling (née Williams; born January 17, 1976, Nassau, Bahamas) is a Bahamian sprint athlete.

She started with a bronze medal at the 2004 IAAF World Indoor Championships in Budapest, Hungary, running a personal best behind Russia's Natalya Nazarova and Olesya Krasnomovets.

In a head-to-head final straight, she proved to be more powerful than the Mexican runner who had been hampered with injuries and trained only on a limited basis prior to the Games.

She also won the gold medal in the 400 meters at 2005 World Championships in Athletics, in a head-to-head race with American 400-meter specialist Sanya Richards.

At the 2006 Commonwealth Games, despite being the favourite, she was beaten unexpectedly both in her semi-final and the final by Christine Ohuruogu of England, claiming silver instead.
