Fred Clarke (October 3, 1872 - August 14, 1960) was a Major League Baseball player and manager at the turn of the 20th century. He was a left fielder and left-handed batter.
Clarke was born in Winterset, Iowa. He joined the Louisville Colonels in 1894 and, in his second season, 1895, asserted himself as one of the team's best hitters, batting .347. In 1897 Clarke took over managerial duties, although the team struggled under his guidance for several years.
In 1900, Clarke joined the Pittsburgh Pirates as a player and manager, roles he would embrace until his retirement in 1915. He finished his career with a .312 batting average and having led his team to four National League pennants (1901, 1902, 1903 and 1909) and one World Series championship (in 1909). The 1903 Pirates lost only 36 games under his guidance, a modern-era record.
Fred Clarke was selected to the Baseball Hall of Fame in 1945. He died in Winfield, Kansas, at the age of 87.
