2016 United States presidential election in Maryland

The 2016 United States presidential election in Maryland was held on Tuesday, November 8, 2016, as part of the 2016 United States presidential election in which all 50 states plus the District of Columbia participated. Maryland voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, businessman Donald Trump, and running mate Indiana Governor Mike Pence against Democratic Party nominee, former Secretary of State Hillary Clinton, and her running mate Virginia Senator Tim Kaine. Maryland has 10 electoral votes in the Electoral College.

Clinton won Maryland with 60.3% of the vote, while Trump received 33.9%. Maryland was among the eleven states (and the District of Columbia) in which Clinton improved on Barack Obama's 2012 raw vote total, although by just 84 votes. Maryland was one of four states in which Clinton received over 60% of the vote, the others being Massachusetts, Hawaii, and California. However, Maryland was the only one of those eleven states to have voted more Democratic in both 2012 and 2016. In this election, Maryland voted 24.32% to the left of the nation at-large.

Clinton continued the tradition of Democratic dominance in the state of Maryland, capturing large majorities of the vote in the densely populated and heavily nonwhite Democratic Baltimore–Washington metropolitan area, while Trump easily outperformed her in more white, sparsely populated regions elsewhere in the state that tend to vote Republican. While Republicans typically win more counties, they are usually swamped by the heavily Democratic counties between Baltimore and Washington. Though Trump won 17 of Maryland's 24 county-level jurisdictions, the state's four largest county-level jurisdictions—Montgomery, Prince George's and Baltimore counties and the City of Baltimore—all broke for Clinton by double digits, enough to deliver the state to her.

Clinton became the first Democrat to win Anne Arundel County, home to the state capital of Annapolis, since Lyndon B. Johnson in 1964. Therefore, Trump became the first Republican to win the White House without carrying Anne Arundel County since Calvin Coolidge in 1924.
