Ensign Williams was a Human Starfleet officer who served aboard the USS Enterprise-D in the mid-2360s.
In 2365, while Lieutenant Worf was on an away mission to Iconia, Ensign Williams served as tactical officer and reported several system failures to Commander Riker.
She was unable to get a lock at the Romulan warbird Haakona because of the malfunctioning systems. Williams smiled when Riker asked for some rocks to throw at the vessel. (TNG: "Contagion")
Ensign Williams was played by Dana Sparks.
Her name comes from the script.
