Thomas Joseph Dowse (August 12, 1866 – December 14, 1946) was a catcher/outfielder who played in Major League Baseball from 1890 through 1892.

In a three-season career, Dowse was a .197 hitter (116-for-590) with 46 RBI without home runs in 160 games played.

Despite his modest numbers, he entered the record books by playing for four different teams in a single season, matching a very uncommon feat set by Harry Wheeler in 1884.

He started his career in 1890 with the Cleveland Spiders of the National League, appearing in 40 games for them while hitting a .208 average.

In 1891 he played for the Columbus Solons of the American Association and posted career-numbers in average (.224), RBI (22), runs (24), and doubles (7).
