James Howard "Jim" Thome (pronounced /ˈtoʊmeɪ/; born August 27, 1970 in Peoria, Illinois) is a Major League Baseball First Baseman for the Los Angeles Dodgers.

Thome was originally drafted by the Cleveland Indians in the 13th round of the 1989 MLB Draft. He made his Major League debut on September 4, 1991 as a third baseman against the Minnesota Twins. He was 2 for 4 in that game, with his first hit coming off pitcher Tom Edens in the fourth inning. He hit his first career home run on October 4 against New York Yankees pitcher Lee Guetterman.

Originally a third baseman, he was shifted to first base when the Indians traded for Matt Williams in 1997.
