2020 United States presidential election in Hawaii

The 2020 United States presidential election in Hawaii was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Hawaii voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Hawaii has four electoral votes in the Electoral College.

Hawaii was the first state in the 2020 election cycle to exceed the voter turnout in 2016, causing the state to attract attention as a representation of an overall trend in increased early voting during the general election.

Biden won Hawaii with 63.7% of the vote, with a 29.5% margin over Trump, who earned 34.3%. Both major parties improved over 2016, when third parties earned nearly 8% of the vote; Biden's percentage of the vote was slightly higher than Hillary Clinton's 62.9%, while Trump improved over his 30.3% share of the 2016 vote. However, Biden's margin of victory was smaller than Clinton's 32.5%. Hawaii was one of three states where Biden won every county, the other two being Massachusetts and Rhode Island. It was the eighth consecutive election that the Democratic nominee carried every county in the state.

Per exit polls by the Associated Press, Biden had support in Hawaii across different ethnic groups, with 63% of whites and 66% of Asians voting for him. Japanese Americans make up a large percentage of the Hawaiian population, and they are among the most Democratic constituencies. However, Trump gained ground on Filipino Americans in the state. Hawaii was the only state in which the electorate was majority-minority in 2020, with Whites comprising only 29% of the electorate.
