Thomas Joseph Lovett (December 7, 1863 – March 19, 1928) was an American professional baseball pitcher.

Brooklyn jumped to the National League in 1890, and that year, Lovett was arguably the best player on the club.

In the World Series, he pitched four complete games and won two of them, as Brooklyn played the Louisville Colonels to a draw.

On June 22, 1891, Lovett pitched a no-hitter against the New York Giants, a 4-0 victory.
