John Allen Miller (born March 14, 1944 in Alhambra, California) is a former Major League Baseball player who played for the 1966 New York Yankees and 1969 Los Angeles Dodgers. He is made famous by the fact he is one of only two players to hit a home run in his first and last major league at-bats. The other is Paul Gillespie. Miller's first and last major league at-bat home runs (off of Lee Stange and Jim Merritt respectively) were the only two home runs he hit in his career.

Following his major league career, Miller played for three seasons in Japan, from 1970 until 1972 for the Chunichi Dragons. There, he primarily played first base, batting .245 with 79 home runs over those three seasons.
