John K. Tener (July 25, 1863 - May 19, 1946) was a Major League Baseball player and, from 1911 to 1915, Governor of Pennsylvania. Born in County Tyrone, Ireland, he immigrated to the United States with his parents, who settled in Pittsburgh, Pennsylvania in 1872. Tener attended the public high schools and was employed by manufacturing firms and corporations in and around Pittsburgh. From 1885 to 1890, he played professional baseball as a pitcher and outfielder.
He entered the banking business in Charleroi, Pennsylvania in 1901, where he was cashier, and later president, of the First National Bank. He was elected as a Republican to the United States House of Representatives and served from March 4, 1909, to January 16, 1911, when he resigned, having been elected Governor of Pennsylvania, an office he held from 1911 to 1915.
From 1914 to 1918, Tener was president of the National League of Professional Baseball Clubs, and in 1931 was elected as director of the Philadelphia National League Baseball Club in 1931. He engaged in the insurance business until his death; he made his home in Charleroi and died in Pittsburgh in 1946, interment taking place in Homewood Cemetery.
