The 2024 Ohio Democratic presidential primary took place on March 19, 2024, as part of the Democratic Party primaries for the 2024 presidential election. 143 delegates to the Democratic National Convention will be allocated to presidential candidates.{{Cite web |title=Ohio Democratic Delegation 2024 |url=https://www.thegreenpapers.com/P24/OH-D |access-date=November 24, 2023 |website=The Green Papers}} The contest was held alongside Arizona, Illinois, and Kansas.

President Biden won every county; but, despite having already dropped out, U.S. Representative Dean Phillips won three delegates. Congressman Phillips was still on the ballot on election day and gained his delegates by meeting the 15% threshold of votes needed to receive a delegate in a congressional district in the state's 2nd, 6th, and 14th districts.{{cite web |last1=Askarinam |first1=Leah |last2=Day |first2=Chad |title=Dean Phillips gains his first delegates.
