The polls will be open from 7 a.m. until 8 p.m. on Tuesday.
Voters in the First State will choose a new governor.
Democrat Matt Meyer and Republican Mike Ramone are both running to replace outgoing Governor John Carney.
Carney won the Democratic primary to become the next mayor of Wilmington.
He has no Republican opposition in the general election.
Democratic Congresswoman Lisa Blunt Rochester faces Republican Eric Hansen for a U.S. Senate seat in Delaware.
If elected, Rochester would be the first woman and first Black person to hold that seat in First State history.
Democratic State Senator Sarah McBride could also make history with a win against Republican John Whalen in the race for Delaware's sole congressional seat.
McBride would be the first openly transgender person elected to the U.S. House of Representatives.
