David Carlous Williams (November 2, 1927 – August 17, 2009) was an American professional baseball player and coach.

Williams was listed as 5 feet 10 inches (1.78 m) tall and 165 pounds (75 kg), and batted and threw right-handed.

On April 23, 1955, Williams severely injured his back in an on-field collision with Jackie Robinson of the Brooklyn Dodgers — the result of a brushback battle between the two bitter rivals.

In the fourth inning, Robinson dropped down a bunt, intending to retaliate for the knockdown pitch by crashing into Maglie as he fielded the ball.

A good contact, free swinger hitter, he collected 164 walks and 144 strikeouts in 1,993 plate appearances.

Immediately following his playing career, Williams coached for the Giants in 1956 and 1957, their final two seasons in New York before their move to San Francisco.
