James Thomas Williams (December 20, 1876 – January 16, 1965) was a second baseman in Major League Baseball from 1899 to 1909.

The power-hitting Williams set several records during his rookie season and led a major league in triples three times.

In 1897, he established himself as a premiere power hitter, slugging 31 home runs for the Western Association's St. Joseph Saints.

He hit more homers than any two other players in the league combined, and he also paced the circuit in slugging percentage and total bases.
