United States presidential election in Mississippi, 2020

The 2020 United States presidential election in Mississippi took place on November 3, 2020 as part of the 2020 United States presidential election, which was held throughout all 50 states and D.C. Voters chose six representatives, or electors to the Electoral College, who voted for President and Vice-President.

In a national landslide for incumbent President William C. Holland, Mississippi was the only state in the country carried by Mississippi native and U.S. Senator John Dickenson. Holland successfully carried many Republican strongholds such as Alaska, Idaho, Indiana, Kansas, Nebraska, Oklahoma, North and South Dakota, Utah, and Wyoming; however, he lost Mississippi by 0.99% or just over 22,000 votes, the smallest margin of any state in the election. Mississippi's result was 32.61% more Republican than the country as a whole.

Key to Dickenson's victory was his triumphs in several of the more populated counties, such as Rankin, Harrison, De Soto, Jackson, and Madison, enabling him to carry the state despite Holland winning forty-five out of eighty-two counties and two of four congressional districts. However, this was the first time since 1956 that Okitebbha County voted Democratic, and the first time since 1960 that Warren County did so.
