The 2020 Oklahoma Democratic presidential primary took place on March 3, 2020, as one of 15 contests scheduled on Super Tuesday in the Democratic Party primaries for the 2020 presidential election, following the South Carolina primary the weekend before. The Oklahoma primary was a semi-closed primary, with the state awarding 43 delegates towards the 2020 Democratic National Convention, of which 37 were pledged delegates allocated on the basis of the results of the primary.

Former vice president Joe Biden won another southern primary by a large margin with almost 39% of the vote and 21 delegates, while senator Bernie Sanders placed second with around 25% and 13 delegates. Former mayor Michael Bloomberg and senator Elizabeth Warren did not reach the threshold, only getting a few district delegates. The election was a remarkable shift from 2016 when Sanders had won nearly every county and easily defeated Hillary Clinton by a double digit margin.
