The 2012 United States presidential election in Connecticut took place on November 6, 2012, as part of the 2012 United States presidential election in which all 50 states plus the District of Columbia participated. Connecticut voters chose seven electors to represent them in the Electoral College via a popular vote pitting incumbent Democratic President Barack Obama and his running mate, Vice President Joe Biden, against Republican challenger and former Massachusetts Governor Mitt Romney and his running mate, Congressman Paul Ryan. Obama and Biden carried Connecticut with 58.1% of the popular vote to Romney's and Ryan's 40.7%, thus winning the state's seven electoral votes. Romney managed to flip the traditionally Republican Litchfield County, which Obama had won in 2008. As of the 2020 United States presidential election, this was the last election that the Democratic presidential nominee won Windham County.

Litchfield County is in northwestern Connecticut, United States. As of the 2020 census, the population was 185,186. The county was named after Lichfield, in England. Litchfield County has the lowest population density of any county in Connecticut and is the state's largest county by area.
