William Henry Holbert (March 14, 1855 – March 20, 1935) was a catcher in the National League and American Association baseball leagues, from 1876 through 1888. He holds the Major League record for career at-bats without a home run, failing to do so in his 2,335 at-bats. However, he was playing in an era when triples were more common than home runs, due to the spacious parks and poor quality of the balls used. When the new Players' League started up in 1890, Holbert was one of the original umpires.
