Thomas Tarlton Brown (September 21, 1860 – October 25, 1927) was an Anglo-American center fielder in Major League Baseball. Born in Liverpool, Lancashire, England, he played for 17 seasons, a career in which he batted .265 while scoring 1,521 runs with 1,951 hits. Upon his retirement he served as an umpire, working mostly in the National League in 1898 and 1901–1902.

In June 1882, Tom signed with the Baltimore Orioles, of the American Association, as non-drafted free agent. As a right fielder, he hit one home run with 23 runs batted in for that season with Baltimore. He was a right fielder for most of his early career, he switched over to center later in his career. That year, the Orioles finished 6th in the league, and Brown was sent to the Columbus Buckeyes in an unknown transaction before the 1883 season. He played two season in Columbus, both of which he hit five home runs and drove in 32 runs. His best season with them occurred in 1884, when he batted .273 and scored 93 runs in 106 games played.

On October 30, 1884, the Buckeyes went under and the team, with all of its players, were purchased by the Pittsburg Alleghenys for a sum of $8,000. Highlights of his two and a half seasons with the Alleghenys include a .307 batting average in 1885 and 51 RBIs in 1886. However, he struggled in 1887 and was released by Pittsburg on August 15. He was picked up by the Indianapolis Hoosiers, of the National League, a few days later, where he hit only .179 in 36 games. While at Indianapolis, Brown became part of the first known platoon arrangement in baseball, as he split time with right-handed hitting Gid Gardner.
