Johannes Peter "Honus" Wagner (; February 24, 1874 – December 6, 1955) was an American baseball shortstop who played 21 seasons in Major League Baseball from 1897 to 1917, almost entirely for the Pittsburgh Pirates. Wagner won eight batting titles, tied for the most in National League history with Tony Gwynn. He also led the league in slugging six times, and in stolen bases five times. Wagner was nicknamed "The Flying Dutchman" due to his superb speed and German heritage (English-speaking people used to use the word Dutch to describe people from both the Netherlands and Germany). This name was a nod to the popular folk-tale made into a famous opera by another Wagner.
In 1936, the Baseball Hall of Fame inducted Wagner as one of the first five members. He received the second-highest vote total, behind Ty Cobb and tied with Babe Ruth.
Although Cobb is frequently cited as the greatest player of the dead-ball era, some contemporaries regarded Wagner as the better all-around player, and most baseball historians consider Wagner to be the greatest shortstop ever. Cobb himself called Wagner "maybe the greatest star ever to take the diamond." Honus Wagner is also the featured player of one of the rarest and most valuable baseball cards in existence.
He is also known as Johannes Peter Wagner.
