James R. Buck (born July 30, 1945) is a member of the Indiana State Senate representing the 21st district.
In 2025, Buck was one of 21 Republican senators to vote against mid-decade redistricting in Indiana, which would have net Republicans an additional 2 seats in the U.S. House of Representatives, prompting criticism from national and state Republicans such as president Donald Trump and governor Mike Braun, who endorsed a primary opponent.
In 2026, Buck lost renomination to Tracey Powell, 35.3%–64.7%.
